There is new information on circulation indices on the site: archive of the circulation indices forecast (SL-AV model) and archive of the atmospheric action centers morphometric characteristics in the Northern Hemisphere.

The circulation indices forecasts are calculated in the base the SL-AV model (Hydrometcenter of Russia) da. The archive covers 2024 and 2025 and contains data for the EA, WA, EU, WP, PNA, NAO, POL, SHI, and AOS indices. 

The archive of the atmospheric action centers morphometric characteristics in the Northern Hemisphere contains sea-level pressure values and center coordinates for the Icelandic Low, Aleutian Low, Azores High, Hawaiian High, and Siberian High starting from January 2025.

The time series of surface air temperature anomalies (since 1960) based on the INM RAS model was updated. The series are presented with the global averaging and averaged  for Northern Eurasia.   

There was an update of the forecasts for 1 year and 1-5 years according to the INM RAS model (INM-CM5). Forecasts include global fields of air surface temperature at 2 m, precipitation, 500 hPa height, and atmospheric pressure at sea level. Forecasts are available by the link https://seakc.meteoinfo.ru/en/forecasts/decadal-forecasts. 

There is a new section on the NEACC website with an archive of circulation index forecasts based on the SL-AV model: https://seakc.meteoinfo.ru/en/archive-of-circulation-indices. The archive currently contains 4-month forecasts of the EA, WA, EU, WP, PNA, NAO, POL, SHI, and AOS indices for 2024 and 2025.
