On Dec. 29, 2018, a weather satellite peering down over the Pacific spotted a cluster of towering thunderheads with extremely cold cloud tops. A recently released study confirms one of the clouds was ...

In the late 20th century scientists observed a cooling at the transition between the troposphere and stratosphere at an altitude of about 15 kilometers. Climate scientists now show that the cooling ...

In a recent study, the authors hypothesize that the Clausius–Clapeyron relation provides a strong constraint on the temperature of the extratropical tropopause and hence the depth of mixing by ...

The impact of two different coupled cirrus microphysics–radiation parameterizations on the zonally averaged temperature and humidity biases in the tropical tropopause layer (TTL) of aMet Office ...

Researchers at the Lawrence Livermore National Laboratory have discovered another fingerprint of human effects on global climate. Recent research has shown that increases in the height of the ...
