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]
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.
The factors that determine tropical cyclone activity are relatively well understood: warmer sea levels are favourable to tropical cyclones, as well as an unstable and moist mid-troposphere, while vertical wind shear suppresses them. All of these factors will change under climate change, but is not always clear which factor dominates. [17]
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.
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 ...
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 ...
The modern, arid Sahara. The Sahara was not a desert during the African humid period. Instead, most of northern Africa was covered by grass, trees, and lakes. The African humid period (AHP; also known by other names) was a climate period in Africa during the late Pleistocene and Holocene geologic epochs, when northern Africa was wetter than today.
Milton, which comes just after the recent catastrophic Hurricane Helene, has strengthened to a Category 4 storm as it approaches Florida’s Gulf Coast and is expected to make landfall late Wednesday.
