Patterns of atmosphere baric fields preceeded to development of extreme thermal modes in the South-Kuril area in summer are identified using the interval approach to their recogni tion. The best recognition rates are noted for the field of AT 500 hPa over the region of East Asia in February, March, May, and June. Extreme cold summer conditions in the South-Kuril area in summer were preceeded by development of AT 500 hPa trough and baric depression at the sea surface over East Asia in these winter and spring months. Warm summer conditions in the South-Kuril area were preceeded by opposite patterns, as AT 500 hPa ridge over the North-West Pacific and high pressure over the Okhotsk Sea, with positive anomalies of H500 height over the North-West Pacific and Kuril Islands.
