Abstract
This study evaluates the stratospheric water vapour distribution and
variability in the Arctic. A FinROSE chemistry transport model simulation
covering the years 1990–2014 is compared to observations (satellite and
frost point hygrometer soundings), and the sources of stratospheric water
vapour are studied. In the simulations, the Arctic water vapour shows decadal
variability with a magnitude of 0.8 ppm. Both observations and the
simulations show an increase in the water vapour concentration in the Arctic
stratosphere after the year 2006, but around 2012 the concentration started
to decrease. Model calculations suggest that this increase in water vapour is
mostly explained by transport-related processes, while the photochemically
produced water vapour plays a relatively smaller role. The increase in water
vapour in the presence of the low winter temperatures in the Arctic
stratosphere led to more frequent occurrence of ice polar stratospheric
clouds (PSCs) in the Arctic vortex. We perform a case study of ice PSC
formation focusing on January 2010 when the polar vortex was unusually cold
and allowed large-scale formation of PSCs. At the same time a large-scale
persistent dehydration was observed. Ice PSCs and dehydration observed at
Sodankylä with accurate water vapour soundings in January and
February 2010 during the LAPBIAT (Lapland Atmosphere–Biosphere facility)
atmospheric measurement campaign were well reproduced by the model. In
particular, both the observed and simulated decrease in water vapour in the
dehydration layer was up to 1.5 ppm.
