Nine daily forecasts of the dew-voint deficiency on the 850, 700, and
500 mb levels during the cold half-year have been calculated up to date.
Figs. 1 and 2 show examples of such fo-recasts. The authors describe the
plotting of nomograms on 850 and 700 r1b levels for cloudiness and pre-
cipitation forecasts (Fig-3). An analysis of forecasts of all weather
processes showed a probability of 801pf. There are 3 figures, 2 tables,
and 6 references: 4 Soviet.

TEXT: A numerical scheme developed by the authors for forecastinp,
the baric field at three levels (300, 500, and 850 mb.,, is
bed. It is based on the known solution of the baro-~.linic~
forecasting given by M.I. Buleyev, and G.I. Marchuk. The main fa----
Tors permitzing the derivation of a 3table numerical solution to
the problem are discussed (the due selection of different.Lat14-rin sp,1-
the presentation of derivatives as final differences, ,he Pap-
proximation. of integrals as final sums, etc,). The resulte of fief
teen trial forecasts computed in the "Strela" machine are cituea
The analysis of these forecast3 testifies to the definitely pra-.~'.
