# Description

1. How to change from the point of view of stability of the thermal stratification of the air impingement winter in the temperate latitudes of the continent to the sea surface, is not covered by ice?
2.Find via aerologic diagram condensation level height (Zc), if the surface of the earth atmosphere pressure P0 = 990 hPa, the temperature T0 = 14 0C, t (d) = 2,2 0C. How to change the height of the condensation level while increasing the dew point?
3.Po given atmospheric pressure P = 1006 hPa temperature t = 26,0 0 C, relative humidity f = 60%, get the mass fractions of saturated steam present under these conditions, the dew point and the dew point deficit.
4.Vychislit moist-adiabatic temperature gradient in the air, which is located at a pressure P = 600 hPa and a temperature t = -10,0 0C. How and why the answer will change at the same pressure, but higher (lower) temperature? Why is it always and moist-adiabatic gradient less suhodiabaticheskogo?
5.Sravnite and analyze thermal characteristics of air, water and soil.
6.Amplituda diurnal temperature of the soil surface was 31.1 0 C, and at a depth of 20 cm of 3.7 0C. Calculate the average temperaturoprovodimost top 20-cm layer of soil.
7.Vychislit thermal conductivity of snow cover at a density of 10 kg 2 / m3. How and why the answer change if the density of the snow resulting in increased caking twice?
8.Maksimum surface temperature observed at 13 h 25 min .In some time theoretically maximum occurs at depths of 20, 40 and 60 cm when the thermal diffusivity at all depths the same and equal 16sm2 / h?
9.Pri what the temperature distribution in the surface layer of the formula for determining the coefficient of turbulent diffusion method can not be applied?
10.Nayti turbulence coefficient at 10 m if t = 0,0 (C), Z (0) = 2 cm, U (2,0) = 3 m / s.
11.Vychislit turbulent flow of heat by the heat balance, if B = 0,47kVt / m2, t (0,5) = 18,2 0C, e (0,5) = 14,0gPa, t (2,0) = 17 9 0C, e (2,0) = 13,6gPa P = 0,02kVt / m2.
12. Calculate the turbulence at a height of 1 m according to the method of heat balance, Stationary and refined methods of turbulent diffusion, using the results of gradient observations at altitudes of 0.2; 0.5; 1.0; 2.0 m. This R-kW / m2, the radiation balance of the active layer; RkVt / m2 heat flux into the soil; t (0C) -Theme-air temperature; e (hPa) -partsialnoe water vapor pressure; u (m / s) velocity of the wind at the appropriate levels.

0.5 16.9 12.4 2.6
1 16.6 12.2 2.9
2 16.2 11.2 3.2
R = 0,59 kW / m2 - the radiation balance of the active layer.
P = 0.06 kW / m2 - heat flux into the soil
e - the partial pressure of water vapor (hPa)
air temperature
- The wind speed at the relevant height.
