Meteorology Midterm Study Guide 2 Section A. Circle the letter corresponding to the best answer. (1 point each) 1. Rainbows result from: a. refraction and reflection of sunlight by water droplets b. reflection of sunlight by oceans and large lakes c. selective scattering of visible light by air molecules d. optical illusion resulting from the limitations of human eyesight 2. At sunset in the middle latitudes, look for a rainbow toward the: a. north b. south c. east d. west 3. If the earth did not have an atmosphere, the sky would appear ___ during the day. a. white b. black c. red d. blue The sky is normally blue because molecules in the atmosphere scatter blue light the most. If there were no atmosphere, there would be no molecules to scatter light and the sky would be black. 4. In the Northern Hemisphere, the wind around a high pressure flows: a. clockwise b. counterclockwise c. northerly d. southerly 5. The force that would cause a stationary parcel of air to begin to move horizontally is called the: a. Coriolis force b. Pressure gradient force c. Centripetal force d. Frictional force 6. On average, the height of the 500 mb level generally ____________ as one goes from the equator to the poles. a. increases b. decreases c. stays the same 7. The net force acting on air which is moving parallel to straight isobars at constant speed is: a. in the direction of motion

Meteorology Midterm Study Guide 2 b. to the right of the wind’s motion in the Northern Hemisphere c. zero d. in a direction opposite the wind’s motion 8. We learned that there are many types of atmospheric circulations. In general, as the size of atmospheric circulations increase, their time scale (i.e., lifetimes): a. increases b. decreases c. stays the same d. varies without relation to the spatial scale 9. A wind blowing at a constant speed parallel to straight line 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
