What Is The General Pattern Of Rainfall In Africa?

The air circulation around the equator is the main driver of the annual rainfall sequence in Africa. Ascending warm and moist air immediately north and south of the equator is sucked into the itcz and transported at altitudes of 10-15 km further north and south of the equator.

What is the pattern of rainfall?

Rainfall pattern means the distribution of rain geographically temporally and seasonally. The tropics receive more rainfall than deserts. Cooler places like the poles receive no rainfall as it is converted to snow before it falls to the ground.

How does the rainfall vary in Africa?

Most of the African continent is semi-arid and hence prone to extreme variations in rainfall from year to year. The extreme droughts that have plagued the Sahel and eastern Africa are particularly well known. … A recovery did occur in the Sahel but to varying degrees across the east-west expanse of the region.

What is the general pattern of precipitation?

The main forms of precipitation include drizzling rain sleet snow ice pellets graupel and hail. Precipitation occurs when a portion of the atmosphere becomes saturated with water vapor (reaching 100% relative humidity) so that the water condenses and “precipitates” or falls.

The South-west monsoon constituted 75% of the total rainfall (June to September) 13% of it by north-east monsoon (October to December) 10% of it by pre monsoon cyclonic rainfall (mainly in April and May and 2% of it by western disturbances (December to February).

What are the 4 types of rainfall?

Types of Rainfall

• Convectional rainfall.
• Orographic or relief rainfall.
• Cyclonic or frontal rainfall.

Why was the pattern of snowfall and rainfall changed?

4. Because of the continuous change in climatic conditions the patterns of snowfall and rainfall have been changing over the years which resulted in severe shortage and drought situations. But in the case of severe climatic conditions farming is restricted to just one harvest season.

Why is there no rain in Africa?

How does global warming affect rainfall patterns?

As temperatures rise and the air becomes warmer more moisture evaporates from land and water into the atmosphere. More moisture in the air generally means we can expect more rain and snow (called precipitation) and more heavy downpours.

What is cyclonic or frontal rainfall?

Cyclonic or Frontal rain: This type of rainfall occurs when warm and cold air meets each other. Since warm air is lighter it rises above the cold air. The rising air is then cooled beyond the saturation point resulting in heavy rainfall. Such rainfall lasts only for few hours.
