Monsoon Winds Monsoon- directional reversal of winds from one season to the next Seasonal shift of the winds Low pressure (summer) – wet High pressure (winter) – dry Asian Monsoon Summer Low pressure and convergence is strong and onshore flow of moisture is large. Cherrapunji, India seasonal rainfall of 82.5 feet in 4 months. land-water differences in heating and cooling similar to large wind systems. Chinook (Foehn) The term Chinook means “snow eater.” Form when air must pass over a mountain range As they flow down the leeward side, air is compressed and heated at a high rate than it cooled when it ascended up the mountain on the windward side. Warm dry winds can damage crops, be a fire hazard and trigger avalanches. Santa Ana Katabatic (drainage) winds Local Winds – respond to local terrain or land-water differences in heating and cooling similar to large wind systems. Santa Ana Forms when high pressure develops over desert regions Air is warmer and can fan forest and brush fires

Unformatted text preview: Land-Sea Breeze Diurnal (daily reversal of wind) Differential heating between land and water Coastal Situation Land and Sea Breeze Are simple examples of how uneven heating and cooling of air can set up convection loops that create local winds. Function of the change in temperature and pressure of the air over land in contrast to that over water. During the day, the land warms the air above it. Warm air moves oceanward aloft. Surface winds bring cool marine air inland at the surface. This creates a convection loop. Coastal Situation Land and Sea Breeze Are simple examples of how uneven heating and cooling of air can set up convection loops that create local winds. Function of the change in temperature and pressure of the air over land in contrast to that over water. During the night: Radiation cooling over land creates a reversed convection loop, developing a land breeze....
