Rich in plants and … temperatures fairly constant throughout the year; annual temperature range of less than 2 o C (extreme south) to about 5 o C (high elevations in far north).

Students and kids can write these points in the exam or in their essay writing competition to grab extra marks. 5. A monsoon is actually a seasonal shift in wind direction and pressure distribution that causes a change in precipitation. 2. Ethiopia: March rainy season "critical" for southern pastoralists. - Wet season - The temperatures rarely drop to freezing - Lots of rain, humidity - Dry season - The temperatures rarely exceed 25 °C - Weather is still cool and cloud covered with fog which provides moisture to nourish the forest.

Physical Characteristics Because the densities of solid wastes vary markedly with geographic location, season of the year, the length of time in storage, great care should be used in selecting typical values. The wet season (sometimes called the rainy season) is the time of year when most of a region's average annual rainfall occurs. For the film, see. The characteristics of the savanna biome. S. I.

In other words, the main contribution to the dry part of the season, in terms of the number of nonrainy days, appears to come from 3–4 day dry spells in the arid regions, as opposed to 1 day dry spells in the humid regions. Rainfall of this season accounts for 70 to 85 percent of the annual total. In tropical rainforests, many plants live as epiphytes to receive the necessary sunlight and moisture to complete their life cycle.
