Abstract: oleward migration of the latitudinal edge of the tropics of 0.25°?3.0° decade?1 has been reported in several recent studies based on satellite and radiosonde data and reanalysis output covering the past ~30 yr. The goal ...

Abstract: irtually all metrics of Atlantic tropical cyclone activity show substantial increases over the past two decades. It is argued here that cooling near the tropical tropopause and the associated decrease in tropical cyclone ...

Abstract: n idealized, dry general circulation model is used to examine the response of the tropospheric circulation to thermal forcings that mimic changes in stratospheric water vapor (SWV). It is found that SWV-like cooling in the ...

Abstract: AbstractIn recent decades, the subtropical edges of Earth?s Hadley circulation have shifted poleward. Some studies have concluded that this observed tropical expansion is occurring more rapidly than predicted by global ...

Abstract: The University of Colorado closed-path tunable diode laser hygrometer (CLH), a new instrument for the in situ measurement of enhanced total water (eTW, the sum of water vapor and condensed water enhanced by a subisokinetic ...

Abstract: Previous studies have documented a poleward shift in the subsiding branches of Earth?s Hadley circulation since 1979 but have disagreed on the causes of these observed changes and the ability of global climate models to ...
