Climatic characteristics of air humidity in the Arctic region from upper-air data

摘要

The results are presented of the analysis of mean values and trends in precipitable water in the Arctic atmosphere determined from the data of 55 aerological stations located northwards of 60A degrees N for 1972-2011. The regions with maximum and minimum mean values and trends are identified. It is demonstrated that the humidity increase took place almost over the whole latitudinal zone in summer. The comparison with similar characteristics obtained by other researchers from the reanalysis data demonstrates good agreement.
