The climate is tropical, temperate, or polar; a function of the Hadley and Ferrell cells.
For example, the ENSO (El Niño Southern Oscillation).
For example, monsoon-related precipitation, such as that of the Bay of Bengal, India.
Ocean or large inland lake (coastal precipitation); presence of salt particles (aerosols) from the ocean.
Continental location with respect to one or more moisture sources (for example, in Arizona, convergence of Pacific and Gulf moisture); lifting through horizontal convergence; frontal lifting.
Summer, fall, winter, spring; determines radiation balance; seasonally driven atmospheric cooling.
Mountain ranges, which act as barriers to the movements of continental air masses, with upwind effects (orographic lifting).
Determined by land-surface albedo, which conditions the near surface-radiation balance and makes possible thermal lifting.
Through volcano eruptions or fires, which increase the load atmospheric particulates, favoring the downwind formation of precipitation.
