FIGURE 7. 13 The formation of a dust devil FIGURE 7.13 The formation of a dust devil. On a hot, dry day, the atmosphere next to the ground becomes unstable. As the heated air rises, wind blowing past an obstruction twists the rising air, forming a rotating column, or dust devil. Air from the sides rushes into the rising column, lifting sand, dust, leaves, or any other loose material from the surface. Fig. 7-13, p.180

FIGURE 7. 4 Development of a sea breeze and a land breeze FIGURE 7.4 Development of a sea breeze and a land breeze. (a) At the surface, a sea breeze blows from the water onto the land, whereas (b) the land breeze blows from the land out over the water. Notice that the pressure at the surface changes more rapidly with the sea breeze. This situation indicates a stronger pressure gradient force and higher winds with a sea breeze. Fig. 7-4, p.173

FIGURE 7.8 Valley breezes blow uphill during the day; mountain breezes blow downhill at night. (The L’s and H’s represent pressure, whereas the purple lines represent surfaces of constant pressure.) Fig. 7-8, p.176

FIGURE 7.12 Surface weather map showing Santa Ana conditions in January. Maximum temperatures for this particular day are given in °F. Observe that the down slope winds blowing into southern California raised temperatures into the upper 80s, while elsewhere temperature readings were much lower. Fig. 7-12, p.179
