Document Summary

Moist air is forced over mountain range. As air rises and cools, condenses to form rain in orographic clouds. Slim slips of strong winds in the tropopause high atmosphere . Pushes air masses around and influences climate- bring rainfall. Polar jet streams (strongest) subtropical jet streams (smaller) High altitude, fast moving westerly winds- they contain jet streams. Rossby waves contorted by coriolis- deflecting jet streams- wind and rain. Air is deflected west- effected by the earth"s rotation. Trade winds get bent or deflected left due to the coriolis effect. Warming of water and low air surface pressure- temperature and rainfall affect location of jet streams. Resistant region of atmospheric high pressure that occurs over north east. Leads to dry and warm conditions in california. Occurs due to la nina and persistent hot water and atmospheric pressure in ocean. Recurring pattern of warm water in pacific causes rainfall- influences into.
