Paper Abstract

With the use of data from AIRS satellite instrument the peculiarities in total column ozone (TCO) and total column water vapor (TCWV) fields associated with the spring and summer atmospheric blocking episodes over European Russia in 2010 were studied. In both of the episodes the extensive areas of negative TCO anomalies as well as those of positive TCWV anomalies were manifested over the blocking region. The local (1°×1°) negative TCO anomalies reached the values of -50 DU and -37 DU during the spring and summer blocks respectively, while the corresponding local positive TCWV anomalies attained 12 kg/m2 and 13 kg/m2. The revealed TCO and TCWV anomalies were mainly caused by the large-scale atmospheric circulation, associated with the omega blocks. In part, the TCO decrease could be the result of the photochemical destruction of ozone in the lower stratosphere due to water vapor advection.
