The Hadley circulation is a key atmospheric circulation pattern in the tropics. It helps even out the temperature between the equator and the poles by moving energy and momentum toward higher ...

Add Yahoo as a preferred source to see more of our stories on Google. Atmospheric rivers are long filaments of moisture that curve poleward. Several are visible in this satellite image. Bin Guan, NASA ...

Dynamical mechanisms for the summer Eurasian circulation trend pattern are investigated by analyzing reanalysis data and conducting numerical model simulations. The daily circulations that resemble ...

This August, Japan and South Korea, particularly Japan, have experienced a dramatic surge in typhoon activity. From August 8 to August 13, within just six days, Typhoons Maria, Son-Tinh, Ampil, and ...

Atmospheric rivers are long, narrow corridors of concentrated water vapor in the atmosphere that transport vast amounts of moisture from the tropics toward mid-latitude and polar regions. These ...

Rainfall fluctuates more vigorously. Why? Scientists say it's because of us. Many people around the world have noticed that rainfall is becoming increasingly erratic. Intense downpours are occurring ...

High above our heads and unseen to the naked eye, rivers of water vapor flow through the atmosphere. These "atmospheric rivers" are crucial to the global water cycle. Astonishingly, they have the ...

Pedro DiNezio receives funding from NSF. One of the big contributors to the record-breaking global temperatures over the past year – El Niño – is now gone, and its opposite, La Niña, is on the way.

Scientists have presented a model that elucidates the chain of physical processes driving interannual Hadley cell expansion in the Northern Hemisphere. The Hadley circulation is a key atmospheric ...
