Study Notes
Weather and Climate: High Pressure and Low Pressure Systems
- Low pressure weather is found in places with higher temperatures, such as the equator, leading to unstable, rainy, and windy conditions due to rising warm, moist air.
- Tropical storms form due to high humidity and ocean temperatures of over 26°C, with water evaporating and coming into contact with cold air to form clouds and low pressure columns.
- Extreme low pressure systems like typhoons have very strong winds due to the decrease in pressure.
- High pressure weather is found in places with lower temperatures, leading to stable, clear skies, and little or no precipitation due to sinking cold, dry air.
- In high pressure weather, daytime is characterized by strong sunlight, clear skies, and heat absorption, while nighttime experiences rapid cooling, condensation, and dew formation.
- High pressure in summer can lead to heavy thunderstorms, flooding, and drought if it remains over an area for a long period, affecting food supplies and causing heatwaves.
- In winter, high pressure weather leads to cold, clear and bright days with fog formation at night due to ground cooling and condensation.
- Frost forms in the evening, and when the temperature drops below freezing, dew freezes, impacting traffic, food shortage for animals, and damage to homes.
- Smog, which causes respiratory-related diseases, occurs in winter when fog forms with no strong wind to carry away suspended particulates.
- High pressure systems bring stability and less precipitation due to sinking cold and dry air, resulting in stable weather conditions.
