Document Summary
Spatial and temporal variability temperature and precipitation patterns vary with location and season, determined by solar illumination, the position of continents, and the resulting atmospheric and oceanic flow. Description of climate until now has been zonal. Minneapolis, and seattle/bordeaux that are at the same latitude (and ~ altitude). Visible on africa, white is dry season, blue is the wet season, some will have two wet/dry season (a longer, a shorter) Weather refers to the day-to-day(hour-to-hour)changes in atmospheric condition(weather forecast) When dealing with weather, we are concerned about temperature, precipitation, winds,etc. in the next few days. these are dictated by the movement of high and low pressure systems, showers, and atmospheric instabilities. Climate is the long term averaged weather, and departures from this average. It is determined by radiation, global circulation, lan, etc. Depends on short time period is the weather, climate is average equality, statistics annually. Temperature and precipitation patterns define what we call the climate.
