Tropical Dry Forest

Abiotic Factors

Temperature

Temperatures are high all year the average temperature is above 24c. Because of its proximity to the coast fluctuations in annual temperatures are only 10-15c. Frost and temperature blow freezing are rare. The air changer from mosit deu to inter-tropical region mixtures in the summer to the dry air because of a subtropical weather front during the winter.

Preciipitation

The dry season is far longer than the brief period of rainfall. There is no set amount of rain it depends on the area. Annual rainfall is antwhere from 10-20cm to 1000-000 cm per year depending on the specific tropicsl dry forest.

soil

The soil in this this area is richer with nutrients, but is more vulnerable to eroison the annaul mean temperature is approximately 81'F or around 27'c. However, in the dry season thive may increase to 99'f, or 37'c.

Dominant Plants

It all starts with the first rains. Like a desert blooming in spring, the first thundershowers in the dry forest produce an outbreak of fresh green leaves. This habitat has literally set its watch by the dry season, and many key ecological processes all take their cue from the arrival of the rains. As the new leaves begin catching sunlight, plant growth, stalled during the dry months, shifts into high gear. The precipitation moistens the leaf litter accumulated on the forest floor, where bacteria and insects (many just awakened from estivation) start the decomposition process that releases nutrients for use by the growing plants. As the rainy season nears its end, trees and other plants drop their leaves and produce a profusion of showy flowers in a fireworks-like display designed to attract as many pollinators as possible. Those that are lucky, who get the timing just right, succeed in having some of their flowers pollinated before the dry season commences.

During the dry season plants sit mostly dormant, drawing on their stored water, perhaps using their green bark to generate some energy, and waiting, waiting for the rains to fall again. Leaf litter dries, and insects, frogs and many others return to their chambers to wait as well. As this dry season reaches its conclusion, those pollinated flowers now produce fruits, which arrive with the first rains. Now there are fruits, and leaves, in abundance, and animals from birds to mammals to insects and lizards begin foraging voraciously to recover weight lost during the dry season, and begin looking for mates. Young are produced quickly, in order to take advantage of the surfeit of fruit and other foods. Soon the forest is teeming with new life, bright green and full of the sounds of animals stocking up in preparation for yet another long, hot dry season.

Temperature and Precipitacion

Temperature

The anual average temperatures of tropical dry forest are 24.3ºc based on research, on the other hand the average precipitation, based on research also, is 55 mm. It is generally warm year-round; it alternaits wet and dry seasons, and it alson consists of rich soil subject to erosion.


The tropical rain forest is a forest of tall trees in a region of year-round warmth. An average of 50 to 260 inches (125 to 660 cm.) of rain falls yearly.

Rain forests belong to the tropical wet climate group. The temperature in a rain forest rarely gets higher than 93 °F (34 °C) or drops below 68 °F (20 °C); average humidity is between 77 and 88%; rainfall is often more than 100 inches a year. There is usually a brief season of less rain. In monsoonal areas, there is a real dry season. Almost all rain forests lie near the equator.

Rainforests now cover less than 6% of Earth's land surface. Scientists estimate that more than half of all the world's plant and animal species live in tropical rain forests. Tropical rainforests produce 40% of Earth's oxygen
