The mean temperature in the layer between 750 and 500 hPa decreases eastward by 4 degrees C per 100 km. If the 750 hPa geostrophic wind is from the southeast at 10 m/s, what is the geostrophic wind speed and direction at 500 hPa? Assume that you are at 40 degrees N

An atmospheric column between the pressure levels 90 and 50 kPa is initially isothermal. The geostrophic wind is 10 m / s and south at 90 kPa, 10 m / s and west at 70 kPa, and 20 m / s and west at 50 kPa. Note: It is assumed that the vertical cooling rate is linear between 90 and 50 kPa and that the thickness of the layer 80 - 60 kPa is constant and equal to 2.25 km....

On a windy day, we can define the wind-chill temperature Twc as the air temperature that would give the same rate of heat loss if experienced on a calm day. Consider a day when the air temperature is 2°C and the wind speed is 12 m/s, giving a convective heat transfer coefficient of 45 W/m2⋅K (compared with 10 W/m2⋅K on a calm day). Assume a person has a 3 mm layer of skin (k = 0.37 W/m⋅K), a body surface...
