Question
A hurricane with a central pressure of 940 hPa is surrounded by a region with a pressure of 1010 hPa.The storm is located over an ocean region. At 200 hPa the depression in the
pressure field vanishes (i.e., the 200-hPa surface is perfectly flat). Estimate the average temperature difference between the center of the hurricane and its surroundings in the layer between the surface and 200 hPa. Assume that the mean temperature of this layer outside the hurricane is 3 °C and ignore the virtual temperature correction.
Explanation / Answer
Answer: The average temperature difference between the centre of the hurricane andits surroundings in the layer between the surface and 200hPa is ~ 12°C.
