The map above displays the monthly average wind climatology for the indicated month and pressure level. Climatological wind vectors are plotted over shading and contours indicating the wind speed (in m/s). The shading and contour interval is 3 m/s. Use the controls on the page to change the month, pressure level, and geographic domain. Quick links to continental geographic domains are listed in the blue menu bar on the left. NCEP is an acronym for the National Centers for Environmental Prediction, US.
