Summary: | For the past few decades increased temperature of Arctic’s atmosphere, where surface air temperature increase is more than twice than global, called “Arctic amplification“, has drawn a lot attention [1]. While many factors as changes in atmospheric heat transport from lower latitudes, sea-ice extent/albedo or cloud cover are suggested as significant contributors, in this study we put our focus on changes in total water vapour (TWV) since water vapour can be an indirect evidence of warming. Data for the period 2003-2009, derived from the AMSUB (NOAA-17) microwave radiometer have been examined. We have found that Arctic as a whole has positive trends in TWV, but we have also found high spatial and seasonal variability with different significance of the changes. |
