Seasonal outlook

Outlook of expected conditions from May to July 2014

The outlook includes the results of seasonal forecasts of Roshydromet (the Hydrometcentre of Russia and Voeikov Main Geophysical Observatory) and other WMO global LRF providers. The outlook is based on global forecast models of Roshydromet; the forecast products of other multi-model forecast centers are reported in the table. This outlook information is of advisory character and must be applied to particular regions taking into account the predictability of meteorological processes, regional climate, and quality of state-of-the-art forecast models.

Temperature regime (near-surface air temperature)

According to the forecasts of the Hydrometcenter of Russia and Main Geophysical Observatory models, the forthcoming 3-month period is expected:

warmer than normal:

over most  of the  of the Western Europe, in the European  Russia, in Georgia, in Turkey, over most of the Kazakhstan and Central Asia, over most  of the Siberia, in Yakutia (except for the  northeast), in the south of the Far East and in Mongolia.

Colder than normal

in the  northeast of the  Yakutia and in the west of the  Chukotka.

Note that:   in the northeast of the European Russia, in the north of Western Siberia and in Chukotka  the models of the Hydrometcenter of Russia and of Main Geophysical Observatory predict different categories of air temperature anomalies.

Precipitation

According to the forecasts of the Hydrometcenter of Russia and of Main Geophysical Observatory, the forthcoming 3-month period is expected with:

precipitation deficit:

in the Portugal, in the  southwest of Spain, in the  southeast and in the northeast of Kazakhstan, in Uzbekistan, in the east of Turkmenistan, in the west  of Mongolia.

exceeding precipitation

in Germany, Austria, Czechia, in the west of Ukraine, in Turkey, in the northeast of the European Russia, in the north of Western Siberia, in northeast of Yakutia, in the south of the Far East and in the east of Mongolia.

In other regions of North Eurasia, the season is expected near to the climate normal.
