Document Summary

The net wind is 90deg to the direction of the wind. The coriolis force deflects moving water to the right in the northern hemisphere and the left in the southern. On exam: weather system: recurring circulation pattern and associated weather. Air mass: large body of air with uniform temp and moisture; surface temperature, environmental lapse rate, surface specific humidity. Over source regions; air masses classified in terms of latitude and surface type. Sharp change in dew point and pressure, clouds will form, precipitation will happen. A cod air mass moves under a warm air mass. Warm air slowly slides over cold air (called overrunning) Warm air forced aloft by two cold fronts. Ground surface is heated during the day, giving rise to the warm moist air, it then cools adiabatically and then condenses into a cloud.
