What are the four rainfall regions based on rain fall distribution both in space and time in ethiopia
The four rainfall regions based on rainfall distribution both in space and time in Ethiopia are as follows:
1. Highland Region: This region experiences high rainfall and is located in the highlands and mountainous areas of the country. It receives a significant amount of rainfall throughout the year, with higher intensity during the wet season.
2. Lowland Arid Region: This region is characterized by low and erratic rainfall. It includes the lowland areas and deserts of Ethiopia, such as the Danakil Depression. The rainfall is highly irregular and unreliable, with long dry spells and occasional flash floods during the rainy season.
3. Dry Savannah Region: This region is semi-arid and experiences moderate rainfall. It covers extensive areas of the country, including the eastern lowlands and the central Rift Valley. The rainfall distribution is marked by a dry season and a short rainy season, with most of the rainfall occurring during the wet season.
4. Wet Savannah Region: This region receives a relatively higher amount of rainfall compared to the dry savannah region. It includes areas such as western Ethiopia and parts of the Gambela region. The rainfall distribution is characterized by a longer wet season and a shorter dry season, with significant precipitation throughout the year.
In Ethiopia, the four rainfall regions based on rainfall distribution in space and time are:
1. Western Lowlands: This region receives rainfall during the summer months from June to September, with an average annual rainfall ranging from 500 mm to 800 mm. The rainfall in this area is relatively consistent throughout the year, with little variability.
2. Southern Rift Valley and Highlands: This region experiences a bimodal rainfall pattern, with two distinct rainy seasons. The first rainy season occurs from March to May, and the second rainy season occurs from September to November. The average annual rainfall in this region ranges from 800 mm to 1500 mm.
3. Central and Eastern Highlands: This region receives rainfall mainly during the summer months from June to September. The average annual rainfall in this area ranges from 800 mm to 1500 mm. The rainfall distribution is more variable compared to the Western Lowlands.
4. Northern Highlands: This region experiences a unimodal rainfall pattern, with a single rainy season from June to September. The average annual rainfall in this area ranges from 800 mm to 1200 mm. The rainfall distribution is relatively consistent, with less variation compared to the other regions.
It is important to note that these regions can have variations in rainfall patterns and amounts from year to year, and this information provides a general overview of the rainfall distribution in Ethiopia.
