Countries by average annual precipitation. Some parts of a country can be much wetter than others, so it is not an accurate depiction of the wettest and driest places on earth. This is a list of countries by average annual precipitation .
Average annual temperatures in equatorial lowlands are around 31 °C (88 °F) during the afternoon and 23 °C (73 °F) around sunrise. Rainfall is very high away from cold ocean current upwelling zones, from 2,500 to 3,500 mm (100 to 140 in) per year. There are about 200 rainy days per year and average annual sunshine hours are around 2,000.
Tropical rainforests have a type of tropical climate (at least 18 C or 64.4 F in their coldest month) in which there is no dry season —all months have an average precipitation value of at least 60 mm (2.4 in). There are no distinct wet or dry seasons as rainfall is high throughout the months. One day in a tropical rainforest climate can be ...
Southern Africa has a transition to subtropical and temperate climates (green and yellow), and more desert or semi-arid regions, centered on Namibia, Botswana, and South Africa. [ 1 ] A map of Africa showing the ecological break around the Sahara Desert. The climate of Africa is a range of climates such as the equatorial climate, the tropical ...
The aim of rainfall climatology is to measure, understand and predict rain distribution across different regions of planet Earth, a factor of air pressure, humidity, topography, cloud type and raindrop size, via direct measurement and remote sensing data acquisition. Current technologies accurately predict rainfall 3–4 days in advance using ...
The Southern Oscillation is the atmospheric component of El Niño. This component is an oscillation in surface air pressure between the tropical eastern and the western Pacific Ocean waters. The El Niño–Southern Oscillation is a single climate phenomenon that periodically fluctuates between three phases: Neutral, La Niña or El Niño. [12]
This is a list of countries and sovereign states by temperature. Average yearly temperature is calculated by averaging the minimum and maximum daily temperatures in the country, averaged for the years 1991 – 2020, from World Bank Group , derived from raw gridded climatologies from the Climatic Research Unit .
The summer rainfall region is the largest, being most of the country north of the coastal areas and the north west arid desert. Rain falls from October to February and is often heavy, with the amount of precipitation increasing from west to east. The summer and winter rainfall region is the Eastern Cape. The arid regions are in the north-west ...
