Intertropical Convergence Zone (ITCZ)

Science / Weather / Intertropical Convergence Zone (ITCZ): An area where the Northern and Southern Hemispheric trade winds converge, usually located between 10 degrees North and South of the equator. It is a broad area of low pressure where both the Coriolis MORE

Tropical Cyclone

Science / Weather / Tropical Cyclone: A warm core low pressure system which develops over tropical, and sometimes subtropical, waters, and has an organized circulation. Depending on sustained surface winds, the system is classified as a t MORE

Subtropical Air

Science / Weather / Subtropical Air: An air mass that forms over the subtropical region. The air is typically warm with a high moisture content due to the low evaporative process. MORE

Tropical Air Mass

Science / Weather / Tropical Air Mass: An air mass that forms in the tropics or subtropics over the low latitudes. Maritime tropical air is produced over oceans and is warm and humid, while continental tropical air is formed over arid regi MORE

Tropical Year

Science / Tides and Currents / Tropical Year: The average period of the revolution of the Earth around the Sun with respect to the vernal equinox. Its length is approximately 3 65.242,2 days. The tropical year determines the cycle of changes in t MORE
