Why is the atmosphere becoming drier? - An investigation of the role of dynamical drivers on recent trends in relative humidity

Autor: Kirsten Maria Florentine Weber, Julie Jones, Kate M Willett, Colin Osborne, Robert Bryant

Relative humidity (RH) over land has declined steeply since 2000. The drying signal is relatively consistent from the edge of the deep tropics to the mid-latitudes of both hemispheres, whereas regions equatorward and poleward show increasing RH trend
