Question

4. (1 pt) True False: The geostrophic wind is directed parallel to isobars with lower pressure to the left in the Northern hemisphere. 5. (1 pt) True False: A cyclone has relatively low pressure at its center 6. (1 pt) True False: The pressure gradient acceleration may be equivalently written as 7. (1 pt) True False: A region of low pressure on a surface of constant altitude is 8. (1 pt) True False: For a given latitude and pressure surface, the geostrophic wind an acceleration "downhill by gravity on a surface of constant pressure equivalent to a region of high geopotential height on a surface of constant pressure will be stronger in regions where the geopotential height contours are closer together 9. (1 pt) True / False: Thermal wind balance states that the horizontal rate of change of the geostrophic wind speed is directly related to the vertical rate of change of temper ature 10. (1 pt) True / False: Temperature typically changes most rapidly with latitude in the vicinity of the jet stream because the wind shear of the zonal wind is typically largest beneath the jet stream

Explanation / Answer

4) false - the geostropic wind is directed parellel to isobars with higher pressure to the left in the north hemisphere

5) true

6) the pressure wont be equivelant but would be higher on surface of down hill

7) true

8) false- the pressure and the flow of the wind will be constant at height contours.

9) true

10) true
