Summarize this article in one sentence.
If your weather map has station models, each one will plot the temperature, dew-point, wind, sea level pressure, pressure tendency, and ongoing weather with a series of symbols. Temperature is generally recorded in Celsius degrees and rainfall is recorded in millimeters. In the US, temperatures are in Fahrenheit and rainfall is measured in inches. Cloud cover is indicated by the circle in the middle; the extent to which it is filled indicates the degree to which the sky is overcast. There are many other lines on weather maps. Two of the most important kinds of lines indicate isotherms and isotachs. Isotherms These are lines on a weather map that connect points through which the isotherm passes have the same temperature. Isotachs These are lines on a weather map that connect points where the isotach passes have the same wind speed. A number on the isobars, such as "1008", is the pressure (in millibars) along that line. The distance between isobars is referred to as the pressure gradient. A large change in pressure over a short distance (i.e. close isobars) indicates strong winds. Wind barbs point in the direction of the wind. Lines or triangles coming off the main line at an angle indicate wind strength: 50 knots for every triangle, 10 knots for every full line, 5 knots for every half line.
Read the station models at each point of observation. Study the lines on the weather map. Analyze the pressure gradient. Analyze wind strength.
