Tropical cyclone
Tropical cyclones, also known as hurricanes or typhoons, are large storm systems that form over warm tropical oceans and are characterized by strong winds that spiral inward toward the eye of the storm. They develop when warm, moist air rises and condenses, releasing latent heat that powers the storm. Tropical cyclones strengthen over warm ocean waters due to evaporation that fuels thunderstorms and heavy rain. They weaken rapidly when moving over land away from their heat source. Major tropical cyclone basins are monitored by regional warning centers that track storms and issue advisories.
the Hurricanes
This document discusses hurricanes, including their structure, formation, and naming conventions. It notes that hurricanes are a type of tropical cyclone that forms over warm ocean waters and features heavy rains and strong winds that spiral inward. The document outlines the typical stages of a hurricane's life cycle from formation to maturity to decay. It also describes the vertical structure of hurricanes and notes key factors like sea surface temperature that enable their development. Finally, the document indicates that meteorological organizations name hurricanes to identify and track them, classifying storms on scales of intensity.
Cyclone
this is a presentation of cyclone.in this ppt, various types of cyclones are given.its effects, formation, different names, types, emergency response on cyclone is given
Midlatitude cyclones
Midlatitude cyclones are large low pressure storm systems that form in the midlatitudes. They develop as warm and cold air masses converge, forming fronts where the air masses meet. As the cyclone moves eastward, the cold front typically advances faster than the storm itself and eventually catches up to the warm front. Meteograms are charts that plot changes in weather conditions over time and can clearly show the passing of fronts and associated changes in temperature, wind, precipitation and other conditions.
Disaster
This document summarizes different types of natural and man-made disasters. It describes natural disasters such as tornadoes, lightning, earthquakes, cyclones, and tsunamis. It provides details on the causes and characteristics of each type of natural disaster. The document also summarizes some common man-made disasters including war, viruses, factory waste, bacteria, and crime. It briefly explains each type of man-made disaster and its impacts.
WATER RESOURCES ENGINEERING MODULE 1 NOTES
This document provides an overview of key concepts in hydrology and water resources engineering. It discusses the hydrologic cycle and its three main processes of evaporation, precipitation, and runoff. It describes different types of precipitation including cyclonic, convective, and orographic precipitation. Measurement of rainfall using rain gauges is also summarized, including factors to consider for the optimal number of rain gauges. Methods for estimating missing precipitation data from nearby rain gauges are outlined, such as the arithmetic mean method, normal ratio method, and inverse distance method.
Cyclone and its types
Cyclones form due to rising warm air that cools and condenses to form clouds. If the air starts spinning horizontally over tropical oceans, it can develop into a tropical depression, storm, and eventually a hurricane or typhoon depending on location and wind speeds. Cyclones cause heavy rainfall, landslides, damage to infrastructure and homes, disruption to ecosystems and agriculture, and harm to human and animal life. Coastal areas need to prepare shelters and strengthen infrastructure to mitigate cyclonic damage.

Hydro metrological hazards
This document defines hydro-meteorological hazards as natural phenomena involving atmospheric, hydrological, or oceanographic processes that can cause loss of life, property damage, economic disruption, or environmental degradation. It provides three examples of hydro-meteorological hazards: floods, which can occur due to heavy rain overwhelming drainage systems; droughts, which are difficult to define but represent temporary climate aberrations; and cyclones, also known as tropical storms or hurricanes, which are intense low-pressure weather systems with winds over 62 kmph.

Eyewall replacement cycle - Wiki
1. Eyewall replacement cycles occur naturally in intense hurricanes when an outer ring of thunderstorms forms and contracts inward, weakening the inner eyewall by reducing its moisture and momentum. This causes the storm to initially weaken before the outer eyewall replaces the inner one.
2. Project Stormfury in the 1960s aimed to artificially trigger this process by seeding storms, but it was later found that eyewall replacement can occur naturally due to hurricane dynamics.
3. Nearly half of all major hurricanes undergo at least one eyewall replacement cycle, during which the storm may fluctuate between categories before re-intensifying with a new eyewall.

1) Aerosols can both decrease and increase rainfall through their effects on cloud microphysics and radiation. They slow the conversion of cloud droplets to raindrops but can invigorate deep convective clouds under certain conditions.
2) Observational studies show that aerosols can completely suppress precipitation from shallow clouds but do not generally reduce rainfall amounts from all cloud types. Heavy aerosol loading has been observed to both suppress rainfall from tropical clouds and invigorate deep convective clouds with warm cloud bases.
3) The document proposes a conceptual model to explain how slowing droplet conversion through increased aerosols can enhance rainfall in deep convective clouds by increasing latent heat release and upward heat transport
2 Introduction To Tropical Cyclones
Tropical Low Pressure Systems are intense low pressure systems with closed circulation also known as hurricanes, typhoons or cyclones. They form over warm ocean waters and have diameters between 200-650km. They contain an eye that is calm at the center surrounded by an eyewall with the strongest winds and thunderstorms. For a disturbance to develop into a full storm, it needs warm ocean waters, atmospheric disturbances, and conditions that allow the transfer of heat away from the storm.

Prepared-by-G2.pptx
This document discusses tropical cyclones and was prepared by a group consisting of 10 members. It defines a tropical cyclone as a rapidly rotating storm system characterized by low pressure, strong winds, and heavy rain from thunderstorms. Tropical cyclones can cause hazards like storm surge, flooding, winds, and tornadoes. The three main types are tropical depressions, tropical storms, and hurricanes. Tropical cyclones impact many areas around the world and cause loss of life and property damage, especially in coastal regions which experience strong winds, flooding, and storm surge.
Cyclone detection
The document discusses parameters for detecting tropical cyclones using satellite data in MATLAB. It analyzes water vapor density maps, infrared temperature images, and cloud patterns to identify potential cyclones. Water vapor density, temperature above 30 degrees, and circular cloud patterns larger than a threshold indicate a cyclone. Maps and images from different satellites are processed and segmented to isolate areas of interest exhibiting these parameters, helping detect cyclones in real time.
Weather and Climate
The document discusses various weather and climate concepts including:
- Weather is the current atmospheric conditions while climate is the average weather over time.
- High pressure systems are associated with clear skies and dry conditions while low pressure systems bring clouds and rain.
- Weather maps use lines of equal pressure (isobars) and symbols to show wind speed and direction helping predict future conditions.
Climatic extremes
Climate Extreme (extreme weather or climate event) refers to the occurrence of a value of a weather or climate variable above (or below) a threshold value near the upper (or lower) ends of the range of observed values of the variable. Extreme weather and climate events, interacting with exposed and vulnerable human and natural systems, can lead to disasters.
Weather and climate by Daniel Portelli 3.02
The document discusses the differences between weather and climate. Weather refers to short-term atmospheric conditions including temperature, precipitation, and humidity that are observed each day and can vary significantly in different locations. Climate describes the average weather patterns over many years in a particular region and influences the typical weather experienced there. Factors like latitude, terrain, proximity to bodies of water, and altitude all impact a region's climate.
Weather cells and weather systems of atmosphere
Jet streams are fast moving air currents in the upper atmosphere. They were first discovered in the 1920s and knowledge of them increased during World War II. There are two main types: polar and subtropical jet streams. Weather features like storms can form when air rises due to low pressure caused by jet streaks. Other weather systems discussed include air masses, frontal systems like cold fronts and warm fronts, mid-latitude cyclones, thunderstorms, tornadoes, and hurricanes.
Cyclone
Cyclones are areas of closed, circular winds rotating in the same direction as the Earth. They form over low pressure systems and can exist on scales from mesocyclones to extra tropical cyclones. Cyclones develop in tropical regions like northern Australia and Southeast Asia between the months of summer, requiring sea surface temperatures of at least 26°C. Cyclones are responsible for loss of life and property damage within 100km of their centers, mainly through strong winds, heavy rainfall, storm surges and tornadoes.
Tropical cyclones and temperate cyclones
There are two main types of cyclones: tropical cyclones and temperate cyclones. Tropical cyclones form in tropical regions between the Tropics of Cancer and Capricorn, originating from warm, moist air masses. Temperate cyclones, also known as extra-tropical cyclones, form in temperate regions between 30-60 degrees latitude due to the convergence of warm and cold air masses along fronts. Some key differences are that tropical cyclones are smaller in size but more intense, with stronger winds near the surface, while temperate cyclones are larger but less severe, with strongest winds at higher elevations.
General Circulation of the Atmosphere
Air Circulation models, three model cells, planetary & local wind are shown here with flexible example.
Cyclone
Cyclones are intense rotating storms that form over bodies of water. They are classified as either extra tropical or tropical cyclones. Tropical cyclones develop over tropical oceans and organize into a surface-level wind circulation. Cyclones form through a process where air rises and causes winds to rotate faster, forming a large swirling storm. Cyclones can cause damage through strong winds, heavy rain, power outages, injury and loss of life, and destruction of crops and vegetation. Preparation and mitigation efforts are important to reduce risks from cyclones.
Cyclones as natural hazards
1. Cyclones are large rotating storm systems that form over warm ocean waters and bring powerful winds, heavy rain, and storm surges. They include hurricanes, typhoons, and tropical storms.
2. Cyclones originate from warm ocean waters that evaporate water vapor into the atmosphere, which condenses and releases heat to power the storm as it rotates due to the Coriolis effect.
3. Cyclones can cause devastating damage from their strong winds, heavy rainfall, and storm surges. Advanced warning and tracking systems help prepare communities for cyclones and mitigate their impacts.
Cyclone Nikhil & Mazar
1) Cyclones form due to low atmospheric pressure and spiral inward in a counterclockwise direction in the Northern Hemisphere. They are known as hurricanes, typhoons, or cyclones depending on the region.
2) Cyclones form from either cold or warm cores and consist of a northern and southern hemisphere surrounding a low pressure center.
3) Major factors for cyclone disasters include human-caused climate change, destruction of coastal barriers, and poverty exacerbating storm impacts.

This paper describes a speed control device for generating electrical energy on an electricity network based on the doubly fed induction generator (DFIG) used for wind power conversion systems. At first, a double-fed induction generator model was constructed. A control law is formulated to govern the flow of energy between the stator of a DFIG and the energy network using three types of controllers: proportional integral (PI), sliding mode controller (SMC) and second order sliding mode controller (SOSMC). Their different results in terms of power reference tracking, reaction to unexpected speed fluctuations, sensitivity to perturbations, and resilience against machine parameter alterations are compared. MATLAB/Simulink was used to conduct the simulations for the preceding study. Multiple simulations have shown very satisfying results, and the investigations demonstrate the efficacy and power-enhancing capabilities of the suggested control system.

precisely delineate tumor boundaries from magnetic resonance imaging (MRI)
scans holds profound implications for diagnosis. This study presents an ensemble convolutional neural network (CNN) with transfer learning, integrating
the state-of-the-art Deeplabv3+ architecture with the ResNet18 backbone. The
model is rigorously trained and evaluated, exhibiting remarkable performance
metrics, including an impressive global accuracy of 99.286%, a high-class accuracy of 82.191%, a mean intersection over union (IoU) of 79.900%, a weighted
IoU of 98.620%, and a Boundary F1 (BF) score of 83.303%. Notably, a detailed comparative analysis with existing methods showcases the superiority of
our proposed model. These findings underscore the model’s competence in precise brain tumor localization, underscoring its potential to revolutionize medical
image analysis and enhance healthcare outcomes. This research paves the way
for future exploration and optimization of advanced CNN models in medical
imaging, emphasizing addressing false positives and resource efficiency.

DEEP LEARNING FOR SMART GRID INTRUSION DETECTION: A HYBRID CNN-LSTM-BASED MODEL
As digital technology becomes more deeply embedded in power systems, protecting the communication
networks of Smart Grids (SG) has emerged as a critical concern. Distributed Network Protocol 3 (DNP3)
represents a multi-tiered application layer protocol extensively utilized in Supervisory Control and Data
Acquisition (SCADA)-based smart grids to facilitate real-time data gathering and control functionalities.
Robust Intrusion Detection Systems (IDS) are necessary for early threat detection and mitigation because
of the interconnection of these networks, which makes them vulnerable to a variety of cyberattacks. To
solve this issue, this paper develops a hybrid Deep Learning (DL) model specifically designed for intrusion
detection in smart grids. The proposed approach is a combination of the Convolutional Neural Network
(CNN) and the Long-Short-Term Memory algorithms (LSTM). We employed a recent intrusion detection
dataset (DNP3), which focuses on unauthorized commands and Denial of Service (DoS) cyberattacks, to
train and test our model. The results of our experiments show that our CNN-LSTM method is much better
at finding smart grid intrusions than other deep learning algorithms used for classification. In addition,
our proposed approach improves accuracy, precision, recall, and F1 score, achieving a high detection
accuracy rate of 99.50%.
Understanding Inductive Bias in Machine Learning
This presentation explores the concept of inductive bias in machine learning. It explains how algorithms come with built-in assumptions and preferences that guide the learning process. You'll learn about the different types of inductive bias and how they can impact the performance and generalizability of machine learning models.
The presentation also covers the positive and negative aspects of inductive bias, along with strategies for mitigating potential drawbacks. We'll explore examples of how bias manifests in algorithms like neural networks and decision trees.
By understanding inductive bias, you can gain valuable insights into how machine learning models work and make informed decisions when building and deploying them.

TIME DIVISION MULTIPLEXING TECHNIQUE FOR COMMUNICATION SYSTEM
Time Division Multiplexing (TDM) is a method of transmitting multiple signals over a single communication channel by dividing the signal into many segments, each having a very short duration of time. These time slots are then allocated to different data streams, allowing multiple signals to share the same transmission medium efficiently. TDM is widely used in telecommunications and data communication systems.
### How TDM Works
1. **Time Slots Allocation**: The core principle of TDM is to assign distinct time slots to each signal. During each time slot, the respective signal is transmitted, and then the process repeats cyclically. For example, if there are four signals to be transmitted, the TDM cycle will divide time into four slots, each assigned to one signal.
2. **Synchronization**: Synchronization is crucial in TDM systems to ensure that the signals are correctly aligned with their respective time slots. Both the transmitter and receiver must be synchronized to avoid any overlap or loss of data. This synchronization is typically maintained by a clock signal that ensures time slots are accurately aligned.
3. **Frame Structure**: TDM data is organized into frames, where each frame consists of a set of time slots. Each frame is repeated at regular intervals, ensuring continuous transmission of data streams. The frame structure helps in managing the data streams and maintaining the synchronization between the transmitter and receiver.
4. **Multiplexer and Demultiplexer**: At the transmitting end, a multiplexer combines multiple input signals into a single composite signal by assigning each signal to a specific time slot. At the receiving end, a demultiplexer separates the composite signal back into individual signals based on their respective time slots.
### Types of TDM
1. **Synchronous TDM**: In synchronous TDM, time slots are pre-assigned to each signal, regardless of whether the signal has data to transmit or not. This can lead to inefficiencies if some time slots remain empty due to the absence of data.
2. **Asynchronous TDM (or Statistical TDM)**: Asynchronous TDM addresses the inefficiencies of synchronous TDM by allocating time slots dynamically based on the presence of data. Time slots are assigned only when there is data to transmit, which optimizes the use of the communication channel.
### Applications of TDM
- **Telecommunications**: TDM is extensively used in telecommunication systems, such as in T1 and E1 lines, where multiple telephone calls are transmitted over a single line by assigning each call to a specific time slot.
- **Digital Audio and Video Broadcasting**: TDM is used in broadcasting systems to transmit multiple audio or video streams over a single channel, ensuring efficient use of bandwidth.
- **Computer Networks**: TDM is used in network protocols and systems to manage the transmission of data from multiple sources over a single network medium.
### Advantages of TDM
