Topics in Pressure, Winds, Storms, and Cyclones
Pressure - Definition and Applications
- Pressure is force per unit area acting perpendicular to a surface
- Smaller area means higher pressure for the same force - explains sharp knives, pointed nails
- Broad straps reduce pressure on shoulders compared to narrow straps
Wind Formation and Air Movement
- Air moves from high pressure to low pressure regions
- Wind speed depends on pressure difference - greater difference means stronger winds
- Land and sea breezes form due to pressure differences over land and water
Storms, Thunderstorms, and Lightning
- Storms form when warm, moist air rises creating low pressure
- Rising air cools, water vapour condenses forming clouds and rain
- Strong upward and downward winds cause friction between water droplets and ice particles
Cyclones - Formation and Impact
- Cyclones form over warm ocean waters through repeated heating and rising of moist air
- Earth's rotation causes spinning motion of the air system
- Eye of cyclone = center with lowest pressure and calm winds
