. There are some other areas at higher latitudes, such as the coast of southeast Florida, United States, and Okinawa, Japan that fall into the tropical rainforest climate category. They experience high mean annual temperatures, small temperature ranges, and rain that falls throughout the year. Regions with this climate are typically designated ''Af'' by the

One day in a tropical rainforest climate can be very similar to the next, while the change in temperature between day and night may be larger than the average change in temperature during the year.

Equatorial climates and tropical trade-wind climates

When tropical rainforest climates are more dominated by the

Intertropical Convergence Zone The Intertropical Convergence Zone (ITCZ , or ICZ), known by sailors as the doldrums or the calms because of its monotonous windless weather, is the area where the northeast and the southeast trade winds converge. It encircles Earth near the t ...

trade winds The trade winds or easterlies are permanent east-to-west prevailing winds that flow in the Earth's equatorial region. The trade winds blow mainly from the northeast in the Northern Hemisphere and from the southeast in the Southern Hemisphere ...

(and with no or rare cyclones), so usually located near the equator, they are also called equatorial climates. Otherwise, when they are more dominated by the trade winds than the ITCZ, they are called tropical trade-wind climates. In pure equatorial climates, the atmospheric pressure is almost constantly low so the horizontal pressure gradient is low. Consequently, the winds are rare and usually weak (except sea and land breezes in coastal areas) while in tropical trade-wind climates, often located at higher latitudes than the equatorial climates, the wind is almost permanent which incidentally explains why rainforest formations are impoverished compared to those of equatorial climates due to their necessary resistance to strong winds accompanying tropical disturbances.
