A PowerPoint about storm surges and how it affects the weather. A brief case study about storm surges in the North Sea and Bangladesh are also included.
Wind is the natural movement of air in the Earth's atmosphere. It is caused by the uneven heating of the Earth's surface by the sun, which creates differences in air pressure. As air moves from areas of high pressure to areas of low pressure, it creates what we perceive as wind. Here are some key characteristics and descriptions of wind:
Direction: Wind is described by the direction from which it is blowing. For example, a north wind blows from the north to the south.
Speed: Wind speed is typically measured in units such as meters per second (m/s), kilometers per hour (km/h), or miles per hour (mph). The speed of the wind can vary widely, from calm conditions with barely perceptible breezes to strong gusts during a storm.
Strength: Wind strength is often classified on various scales, such as the Beaufort Scale, which ranges from calm (0) to hurricane force (12). Each level on the scale corresponds to a range of wind speeds and their effects on the environment.
Gusts: Wind gusts are sudden, brief increases in wind speed that can be significantly stronger than the prevailing wind. Gusts are often associated with weather events like thunderstorms or frontal passages.
Effects: Wind can have various effects on the environment, including:
Erosion: Strong winds can erode soil and affect the landscape over time.
Transportation: Wind can impact travel, especially for vehicles like airplanes and sailboats.
Weather: Wind plays a crucial role in weather patterns, helping to distribute heat and moisture around the globe.
Energy: Wind can be harnessed as a renewable energy source through wind turbines to generate electricity.
Local Patterns: Wind patterns can vary greatly depending on geographic location and terrain. For example, coastal areas often experience onshore and offshore winds influenced by the proximity of the ocean, while mountainous regions may have unique wind patterns due to the interaction with the terrain.
Wind Chill: Wind can make the air feel colder than the actual temperature because it enhances heat loss from the body. This effect is known as wind chill, and it's important to consider in cold weather.
Windsocks and Wind Vanes: Wind direction is often indicated using windsocks or wind vanes, which are instruments that show the prevailing wind direction.
Wind in Meteorology: Meteorologists study wind patterns and speeds as a critical part of weather forecasting. Understanding wind helps predict weather changes, storm development, and atmospheric circulation.
In summary, wind is the movement of air caused by differences in air pressure, and it plays a vital role in our daily lives, weather patterns, and various natural processes.
Horizontal Distribution & Differences of Temperature
If the Earth was a homogeneous body without the present land/ocean distribution, its temperature distribution would be strictly latitudinal. However, the Earth is more complex than this, being composed of a mosaic of land and water. This mosaic causes latitudinal (horizontal) zonation of temperature to be disrupted spatially.

This presentation provides a briefing on how to upload submissions and documents in Google Classroom. It was prepared as part of an orientation for new Sainik School in-service teacher trainees. As a training officer, my goal is to ensure that you are comfortable and proficient with this essential tool for managing assignments and fostering student engagement.
Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

How to Make a Field invisible in Odoo 17Celine George
It is possible to hide or invisible some fields in odoo. Commonly using “invisible” attribute in the field definition to invisible the fields. This slide will show how to make a field invisible in odoo 17.
We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.

Synthetic Fiber Construction in lab .pptxPavel ( NSTU)
Synthetic fiber production is a fascinating and complex field that blends chemistry, engineering, and environmental science. By understanding these aspects, students can gain a comprehensive view of synthetic fiber production, its impact on society and the environment, and the potential for future innovations. Synthetic fibers play a crucial role in modern society, impacting various aspects of daily life, industry, and the environment. ynthetic fibers are integral to modern life, offering a range of benefits from cost-effectiveness and versatility to innovative applications and performance characteristics. While they pose environmental challenges, ongoing research and development aim to create more sustainable and eco-friendly alternatives. Understanding the importance of synthetic fibers helps in appreciating their role in the economy, industry, and daily life, while also emphasizing the need for sustainable practices and innovation.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.
