Fig. 3.2. Station model for plotted surface observations. Note that the second digit of the wind direction is indicated — in this example, a wind fzom 210 deg has a “2” shown. Wind speeds are in kts, temperature in deg F, altimeter setting in hundredths of an inch of mercury (leading digit suppressed — in this example, 29.57 in Hg = 957) and 3-h pressure tendencies in tenths of a millibar (down 1.5 mb over past 3 h = -15).
