Doldrums, also called equatorial calms, are equatorial regions of light ocean currents and winds within the intertropical convergence zone (ITCZ), a belt of converging winds and rising air encircling Earth near the Equator. They occur along the Equator in the Indian and western Pacific oceans and slightly north of the Equator off the African and Central American west coasts.
Chinook winds, or simply Chinooks, are föhn winds in the interior West of North America, where the Canadian Prairies and Great Plains meet various mountain ranges, although the original usage is in reference to wet, warm coastal winds in the Pacific Northwest.
