Precipitation has becoming more extremes, higher intensity and more frequent convective at the expenses of none-convective type in all seasons and less frequent during summer under a warming climate. These changes seem to be independent of the changes in total precipitation. As a consequence, our climate is more prom to drought or flooding over extra-tropical regions. Both drought and flooding are also related to the duration of dry and wet spells, which has been less researched. This study examines the changes in duration of wet and dry spells that are correlated with seasonal air temperatures using historical 517 stations over Russia. The focus is on the characteristics and profiles of changing duration of dry spells that are associated with air temperature in summer. The possible connection of this change to that of other precipitation characteristics are also explore.
