HYDROMETEOROLOGICAL HAZARDs and other related topics.pptxRaquelLansangan
Hydrometeorological hazards are natural events or phenomena that arise from the interaction of the Earth's atmosphere and water cycle, resulting in potentially destructive or harmful impacts on human societies and the environment. These hazards encompass a wide range of phenomena, from relatively localized events such as floods and landslides to large-scale events like hurricanes and droughts. Here's a detailed description of some common hydrometeorological hazards:
1. **Floods**: Floods occur when there is an overflow of water onto land that is normally dry. This can happen due to heavy rainfall, rapid snowmelt, storm surges, or the breaching of dams or levees. Floods can cause extensive damage to infrastructure, agriculture, and homes, as well as loss of life.
2. **Hurricanes and Typhoons**: These are powerful tropical cyclones characterized by strong winds, heavy rainfall, and storm surges. Hurricanes form over the Atlantic Ocean and eastern Pacific Ocean, while typhoons occur over the western Pacific Ocean. These storms can cause widespread destruction, including damage from high winds, flooding, and coastal erosion.
3. **Droughts**: Droughts are prolonged periods of abnormally low precipitation, leading to water shortages and environmental stress. Droughts can have significant impacts on agriculture, water supplies, and ecosystems, affecting both rural and urban communities.
4. **Tornadoes**: Tornadoes are violently rotating columns of air that extend from thunderstorms to the ground. They are often associated with severe thunderstorms and can cause extensive damage to buildings, infrastructure, and vegetation in their path.
5. **Landslides**: Landslides occur when slopes of hills or mountains become unstable and collapse, often triggered by heavy rainfall or earthquakes. Landslides can block roads, destroy buildings, and pose serious risks to human life in affected areas.
6. **Blizzards**: Blizzards are severe winter storms characterized by heavy snowfall, strong winds, and low visibility. They can cause transportation disruptions, power outages, and hypothermia, particularly in regions unaccustomed to such extreme weather conditions.
7. **Heatwaves**: Heatwaves are prolonged periods of excessively hot weather, often accompanied by high humidity. Heatwaves can lead to heat-related illnesses and deaths, particularly among vulnerable populations such as the elderly, infants, and those with pre-existing health conditions.
These hydrometeorological hazards pose significant challenges for disaster preparedness, response, and recovery efforts. Effective mitigation measures, including early warning systems, land-use planning, and infrastructure development, are crucial for reducing the impacts of these hazards on communities and promoting resilience in the face of natural disasters.
Hydrometeorological hazard is a process or phenomenon of atmospheric, hydrological or oceanographic nature that may cause loss of life, injury or other health impacts, property damage, loss of livelihoods and services, social and economic disruption, or environmental damage.

5.1 The concept of weather and climate
Both weather and climate are concepts about atmospheric conditions. The basic difference on them is duration and areal coverage.
Weather is atmospheric condition observed in a very specific area with a short term fluctuation, while
Climate is a prolonged(30-35years) atmospheric condition observed in a relatively wider geographic area.
Weather condition likely changed hour to hour, in a daily base or weakly but climate is relatively permanent.
Elements of Weather and Climate
Elements(components) of weather and climate are the following variables
Atmospheric temperature (how cold or hot is the atmosphere)
Precipitation (any kind of moisture falling from the atmosphere to the ground, mostly rainfall)
Air pressure (the weight exerted by the air)
Humidity (the level or proportion of water vapor within the atmosphere)
Sunshine (the duration and intensity of solar heat as well as light)
Wind (horizontal motion of air)
Professional air quality monitoring systems provide immediate, on-site data for analysis, compliance, and decision-making.
Monitor common gases, weather parameters, particulates.

Observation of Io’s Resurfacing via Plume Deposition Using Ground-based Adapt...Sérgio Sacani
Since volcanic activity was first discovered on Io from Voyager images in 1979, changes
on Io’s surface have been monitored from both spacecraft and ground-based telescopes.
Here, we present the highest spatial resolution images of Io ever obtained from a groundbased telescope. These images, acquired by the SHARK-VIS instrument on the Large
Binocular Telescope, show evidence of a major resurfacing event on Io’s trailing hemisphere. When compared to the most recent spacecraft images, the SHARK-VIS images
show that a plume deposit from a powerful eruption at Pillan Patera has covered part
of the long-lived Pele plume deposit. Although this type of resurfacing event may be common on Io, few have been detected due to the rarity of spacecraft visits and the previously low spatial resolution available from Earth-based telescopes. The SHARK-VIS instrument ushers in a new era of high resolution imaging of Io’s surface using adaptive
optics at visible wavelengths.
Richard's aventures in two entangled wonderlandsRichard Gill
Since the loophole-free Bell experiments of 2020 and the Nobel prizes in physics of 2022, critics of Bell's work have retreated to the fortress of super-determinism. Now, super-determinism is a derogatory word - it just means "determinism". Palmer, Hance and Hossenfelder argue that quantum mechanics and determinism are not incompatible, using a sophisticated mathematical construction based on a subtle thinning of allowed states and measurements in quantum mechanics, such that what is left appears to make Bell's argument fail, without altering the empirical predictions of quantum mechanics. I think however that it is a smoke screen, and the slogan "lost in math" comes to my mind. I will discuss some other recent disproofs of Bell's theorem using the language of causality based on causal graphs. Causal thinking is also central to law and justice. I will mention surprising connections to my work on serial killer nurse cases, in particular the Dutch case of Lucia de Berk and the current UK case of Lucy Letby.
A brief information about the SCOP protein database used in bioinformatics.
The Structural Classification of Proteins (SCOP) database is a comprehensive and authoritative resource for the structural and evolutionary relationships of proteins. It provides a detailed and curated classification of protein structures, grouping them into families, superfamilies, and folds based on their structural and sequence similarities.
