1 Factors that drive atmospheric processes Climate ControlsFactors 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. WaterBecause 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 CurrentsSea-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 WindsThe Earth's average pressure patterns and resulting winds influence climate patterns by:affecting temperature and moisturecausing areas of surface convergence and divergenceConverging – in the North (or South) cause moderating effectsTemperatures can vary from day to dayAt the equator, have a moderating effect, cooling an otherwise hot location
