1 Factors that drive atmospheric processes
Climate Controls Factors that drive atmospheric processes

2 Latitude Latitude is a fundamental control on every climate.
It affects temperature by influencing the seasonal range in solar intensity. It influences precipitation in as much as evaporation is temperature dependent.

3 Land vs. Water Because land heats and cools faster and more intensely than water… continental locations have a larger seasonal temperature range than maritime locations. Maritime locations often have more precipitation because of their proximity to a large moisture source.

4 Ocean Currents Sea-surface temperature influences air temperature as the ocean exchanges heat with the overlying atmosphere. It also influences evaporation rates which are generally higher where sea-surface temperature is higher.

5 Mountains and Climate Temperature generally decreases with altitude.
Mountains also affect seasonal precipitation patterns. Windward side receives more precipitation than the leeward side (rain shadow).

6 Pressure and Winds The Earth's average pressure patterns and resulting winds influence climate patterns by: affecting temperature and moisture causing areas of surface convergence and divergence Converging – in the North (or South) cause moderating effects Temperatures can vary from day to day At the equator, have a moderating effect, cooling an otherwise hot location
