Seasonal tropical forest

Tropical seasonal climate sub-types: (note: Af in light green is Tropical rainforest)

Seasonal tropical forest, also known as moist deciduous, semi-evergreen seasonal, tropical mixed or monsoon

tropical wet savannah (Aw/As) climates (as in the Köppen climate classification). Drier forests in the Aw climate zone are typically deciduous and placed in the Tropical dry forest biome: with further transitional zones (ecotones) of savannah woodland then tropical and subtropical grasslands, savannas, and shrublands
.

Distribution

Extreme differences are very much evident between the wet and dry seasons in a tropical seasonal forest. The image to the left shows Bhawal National Park in central Bangladesh during the dry season, while the image to the right depicts the same area during monsoon season.

Seasonal (mixed) tropical forests can be found in many parts of the

tropical zone
, with examples found in:

Climate

The climate of seasonal forests is typically controlled by a system called the Intertropical Convergence Zone (ITCZ), located near the equator and created by the convergence of the trade winds from the Northern and Southern Hemispheres. The position of these bands vary seasonally, moving north in the northern summer and south in the northern winter, and ultimately controlling the wet and dry seasons in the tropics.[7] These regions appear to have experienced strong warming, at a mean rate of 0.26 degrees Celsius per decade, which coincides with a global rise in temperature resulting from the

anthropogenic warming increases the intensity and frequency of ENSO will increase, rendering tropical rainforest regions susceptible to stress and increased mortality of trees and other plants.[8]

Structure

As with

and secondary can also be problematic, since the species mixture is influenced by factors such as soil depth and climate, as well as human interference.

Characteristic biology

The fauna and flora of seasonal tropical mixed forest are usually distinctive. Examples of the biodiversity and habitat type are often well described for National Parks in:
