Earth Science 20 - Midterm Examination 2 v1 – Winter 2009 1/6 NAME:_______________________________________ Circle the letter corresponding to the best answer. 1. The blue color of the sky is due to: a. selective scattering of visible light by air molecules b. reflection of sunlight off the earth’s oceans c. transmission of visible light through the ozone layer d. the filtering effect of water vapor in the earth’s atmosphere 2. The main reason Santa Ana winds tend to be warm is because: a. latent heat is released in rising air b. sinking air warms by compression c. condensation occurs d. solar heating warms the air 3. In Honolulu, Hawaii (latitude 21°N), you would most likely experience winds blowing from the: a. northeast b. south c. southwest d. west 4. One of the effects of El Nino is a shifting of convective precipitation in the tropical Pacific Ocean. During a major El Nino event, where would you expect to see the largest positive precipitation anomaly? a. over the region of largest negative SST anomaly b. over the region of largest positive SST anomaly c. over small islands regardless of SST anomalies d. over regions where the SST is equal to the long-term mean 5. The force exerted by the wind on a stationary object is proportional to the square of the wind speed (Force proportional to V 2 ). If the wind speed doubles, the drag force increases by a factor of: a. 1 b. 2 c. 4 d. 8 6. Clouds and precipitation are frequently found on the downwind side of a large lake. This would indicate that the surface air on the downwind side is: a. diverging and rising b. diverging and sinking c. converging and rising d. converging and sinking

Earth Science 20 - Midterm Examination 2 v1 – Winter 2009 2/6 7. In a sea-breeze circulation, the wind near the surface is directed: a. from the land towards the ocean b. from the ocean towards the land c. from north to south d. offshore 8. A wind blowing at a constant speed parallel to straight and parallel isobars is a geostrophic wind. This wind is produced by a balance between: a. the gravitational force and the pressure gradient force b. the gravitational force and the Coriolis force c. the Coriolis force and the pressure gradient force d. the pressure gradient force and the frictional force 9. Surface winds blow across the isobars at an angle due to: a. the Coriolis force
