GEOG 131 Lecture Notes - Lecture 16: Water Vapor, Dew Point Depression, Adiabatic Process
Document Summary
4. 4: dew and dew point, dew point a. i. Humid air higher dew point temp than less humid air a. iv. Cloud or fog is air that has its temp lowered to dew point temperature: dew = drops of condensed water out of atmosphere, dew point depression c. i. Difference between air temperature and dew point: dew points and temperature in jan d. i. Average dew point temp in january is typically lower than the average temperature in january d. ii. Nearly the same washington and vermont nearly continuous cloud cover d. iii. High dew points in florida = moisture = energy for evaporation: dew points and temp in july e. i. Eastern us (especially southeaster us) has higher dew point temp e. ii. Western us lower t dew point and higher dew point depression. 4. 5, 4. 6a, 4. 16: air parcels, body of air that has specific temperature and humidity characteristics, density determined by temperature b. i.
