EESA09H3 Lecture Notes - Tropical Storm Grace, Climatology, Latent Heat
Document Summary
El nino (first component of enso, ocean part) Sothern oscillation (second part of enso, atmospheric part) Strong wind blowing west along equatorial pacific, causes warm water in to the pacific. Warm surface water = conditions for big storm in eastern pacific. Cold water rises causing high amounts of warm water in eastern equatorial pacific. Trade winds waken warm water masses, form western pacific to eastern. *refer to lec notes for examples of hurricanes. 60 required) , occure every 4-7 days in season. Define: low frontal system, (35 km range, low intense winds. Cold air pressure in warm air, precipitation along front,15-25 knot speeds. Warm air pushing into cold air mass, little precipitation. Cold front catches up with warm front, warm air above surface, little precepitiation. Polar front region b/w polar & ferrel cells. Boundary that separates cold air from latitude air. Low pressure or cyclone are required weather. Cold front pushes cold air to south, and warm air to north.
