abstract = {During the StratoClim Geophysica campaign, air with total
water mixing ratios up to 200 ppmv and ozone up to
250 ppbv was observed within the Asian summer monsoon
anticyclone up to 1.7 km above the local cold-point
tropopause (CPT). To investigate the temporal evolution of
enhanced water vapor being transported into the
stratosphere, we conduct forward trajectory simulations
using both a microphysical and an idealized freeze-drying
model. The models are initialized at the measurement
locations and the evolution of water vapor and ice is
compared with satellite observations of MLS and CALIPSO. Our
results show that these extremely high water vapor values
observed above the CPT are very likely to undergo
significant further freeze-drying due to experiencing
extremely cold temperatures while circulating in the
anticyclonic “dehydration carousel”. We also use the
Lagrangian dry point (LDP) of the merged back-and-forward
trajectories to reconstruct the water vapor fields. The
results show that the extremely high water vapor mixed with
the stratospheric air has a negligible impact on the overall
water vapor budget. The LDP mixing ratios are a better proxy
for the large-scale water vapor distributions in the
stratosphere during this period.},
