How is vertical shear of zonal wind related to temperature?

The thermal wind relation states that vertical shear of the zonal wind is proportional to the meridional gradient of temperature and inversely proportional to the Coriolis parameter. The temperature gradient in much of the troposphere is directed equatorward, an orientation implying westerly wind shear.

When does a zonal mean wind reversal occur?

The World Meteorological Organization definition of a major sudden stratospheric warming requires a winter zonal mean wind reversal at 10 hPa. A rapid decrease in wind speed but without a reversal in the temperature gradient is called a minor warming.

What are the seasonal averages of zonal winds?

Zonal mean zonal wind (solid contours; in m s −1) with potential temperature (dashed contours; in Kelvin) for seasonal averages (a) December–February and (b) June–August. Areas of easterly winds are shaded. NCEP/NCAR reanalysis data from 1979 to 1999. 1.

Where does the zonal wind climatology come from?

The monthly zonal wind climatology is derived from the UARS Reference Atmosphere Project (URAP), combining results from METO analyses with winds the UARS High Resolution Doppler Imager (HRDI). Details from the URAP winds are described in Swinbank and Ortland (2003).
