Research Abstract

The long-term trend of the water concentration in the tropical stratosphere has been estimated from in situ observations by radiosondes.Supersaturations close to 80 % in relative humidity with respect to ice have been observed in cirrus clouds advected horizontally in the Tropical Tropopause Layer (TTL). General features of dehydration associated with horizontal advection for the air parcels slowly ascending in the TTL have been observationally described for the first time by investigating the water mixing ratio of the observed air parcels and their minimum saturation mixing ratio estimated along the trajectories upstream.
