The African humid period was caused by a stronger West African Monsoon [125] directed by changes in solar irradiance and in albedo feedbacks. [17] These led to increased moisture import from both the equatorial Atlantic into West Africa, as well as from the North Atlantic and the Mediterranean Sea towards the Mediterranean coasts of Africa.

A study from 2022 concluded: "Clearly the existence of a future tipping threshold for the WAM (West African Monsoon) and Sahel remains uncertain as does its sign but given multiple past abrupt shifts, known weaknesses in current models, and huge regional impacts but modest global climate feedback, we retain the Sahel/WAM as a potential regional ...
the Atlantic multidecadal oscillation – A pattern of variability in the North Atlantic of about 55 to 70 years, with effects on rainfall, droughts and hurricane frequency and intensity. [33] North African climate cycles – climate variation driven by the North African Monsoon, with a period of tens of thousands of years. [34]
Of the 197 hurricanes classified as Category 5 from 1980 to 2021, five fit the description of a hypothetical Category 6 hurricane: Typhoon Haiyan in 2013, Hurricane Patricia in 2015, Typhoon ...
The major monsoon systems of the world consist of the West African, Asian–Australian, the North American, and South American monsoons. The term was first used in English in British India and neighboring countries to refer to the big seasonal winds blowing from the Bay of Bengal and Arabian Sea in the southwest bringing heavy rainfall to the area.
The climate of Africa is a range of climates such as the equatorial climate, the tropical wet and dry climate, the tropical monsoon climate, the semi-arid climate (semi-desert and steppe), the desert climate (hyper-arid and arid), the humid subtropical climate, and the subtropical highland climate. Temperate climates are rare across the ...
Researchers examined how particulate air pollution, or aerosols, and climate change have affected tropical cyclones across the planet over the past 40 years in a new study from the National ...
Depending on its location and strength, a tropical cyclone is called a hurricane (/ ˈ h ʌr ɪ k ən,-k eɪ n /), typhoon (/ t aɪ ˈ f uː n /), tropical storm, cyclonic storm, tropical depression, or simply cyclone. A hurricane is a strong tropical cyclone that occurs in the Atlantic Ocean or northeastern Pacific Ocean.
