Except for wind vectors, the following atmospheric variables can be contoured (line) or contoured with the areas between contour levels filled with color (fill). One of the mandatory pressure levels must be selected.
Temperature (°C) Monthly average air temperature on the selected level. Minimum temperature (°C) Monthly average minimum air temperature (minimum of 8 3-hourly temperatures) on the selected level. Maximum temperature (°C) Monthly average maximum air temperature (maximum of 8 3-hourly temperatures) on the selected level. Mixing ratio (g kg-1) Monthly average mixing ratio on the selected level. U-component (m s-1) Monthly average zonal wind component on the selected level. V-component (m s-1) Monthly average meridional wind component on the selected level. Horizontal wind speed (m s-1) Monthly average wind speed on the selected level. Vertical velocity (m s-1) Monthly average vertical velocity on the selected level. Wind Vector Wind vectors (magnitude and direction) on the selected level can be plotted as arrows or as meteorological wind barbs.
