Abstract:

The distribution of wind shear from the surface to 25 kilometers along 80 deg west longitude in the northern hemisphere is examined and is compared with the distributions of the other meteorological parameters. Cross sections of the mean and standard deviation of wind shear and wind speed are presented for each month. Monthly mean cross sections of temperature and density are also given. Time sections of mean wind shear and mean wind speed are given for four stations. In all seasons, very large shears are found near the surface at all latitudes and near the tropopause in low and middle latitudes. Minimum shears are consistently found near 5 kilometers. Largest wind shears in the upper troposphere at a station do not necessarily occur in the same season as maximum wind speeds. In the troposphere above the friction layer, and in much of the stratosphere, wind direction changes are of greater relative importance as an expression of baroclinicity in the summer than in the winter.
