Question

68 20. A series of strong thunderstorms forms in the Texas panhandle in the middle of May. The temperature at this time in Chickasha, Oklahoma is 25° C. The storms increase in strength and begin to rotate as they move northeast. The line of storms eventually produces several tornadoes along with golf ball sized hail. Dozens of homeowners in Chickasha receive damage to their homes and vehicles. Following the storms, the temperature in Chickasha falls to 21° c. what type of lifting mechanism is likely responsible for this weather pattern? 21. The next several questions are in relation to the following statement: On the windward side of the Cascade Mountain Range, the average annual precipitation in Seattle, Washington is 94 cm. In Ellensburg, roughly 173 km to the east of Seatle on the leeward side of the Cascade Mountain Range, the average annual precipitation is 0.23 cm 21a. Which lifting mechanism is responsible for this temperature change? 21b. As air moves up the windward side of the mountain, at which adiabatic rate does the temperature change? 21c. As air moves down the lceward side of the mountain, at which adiabatic rate does the temperature change? 21d. The Cascade Range between Seattle and Ellensburg reaches an elevation of approximately 2.5 km. Scattle has an elevation at sea-level while Ellensburg sits near 500 m. The air passing over Scattle has a temperature of 20° C and a dew-point temperature of 5o C. In the figure below, identify the new temperatures as the air moves over the Mount St. elens towards Ellensburg. 2500 m 2000 m 1500 m 1500 m 1000 m 1000 m Ellensburg Seattle 500 m 20PC 0 m
