  • Surface weather charts summarize weather conditions that can affect your life. Where is it raining, snowing, windy, hot or humid? More than just plots of raw weather reports, you can analyze maps to highlight key features including airmasses, centers of low- and high-pressure, and fronts (Fig. 9.1). In this chapter you will learn how to interpret weather reports, and how to analyze surface weather maps.

    Figure 9.1 Idealized surface weather map showing high (H) and low (L) pressure centers, isobars (thin black lines), and fronts (red or blue heavy solid lines) in the N. Hemisphere. Vectors indicate near-surface wind. Dashed line is a trough of low pressure. cP indicates a continental polar airmass; mT indicates a maritime tropical airmass.
