Except for wind vectors, the following near-surface variables can be contoured (line) or contoured with the areas between contour levels filled with color (fill).
Temperature (°C) Monthly average 2m temperature. Precipitation (mm) Monthly total precipitation. Mean sea-level pressure (hPa) Monthly average atmospheric pressure reduced to sea level. Minimum temperature (°C) Monthly average minimum 2m temperature (minimum of 8 3-hourly temperatures) Maximum temperature (°C) Monthly average maximum 2m temperature (maximum of 8 3-hourly temperatures) Mixing ratio (g kg-1) Monthly average 2m mixing ratio. Surface pressure (hPa) Monthly average atmospheric pressure. Snow water equivalent [SWE] (kg -2) Monthly average amount of water in snowpack. Mid-month SWE (kg -2) Amount of water in snowpack on the 15th of the month. U-component (m s-1) Monthly average zonal wind component. V-component (m s-1) Monthly average meridional wind component. Wind speed (m s-1) Monthly average wind speed. Wind Vector Wind vectors (magnitude and direction) can be plotted as arrows or as meteorological wind barbs.
