Depression Klaus- 2009Slide2
You will be able to describe the passage of depression Klaus over the 23
rd and 24th of January.
Objectives
You will be able to identify the different stages in the development of depression Klaus using satellite and temperature maps.
You will be able to offer reasons for why depression Klaus was particularly intense compared to other storms.Slide3
Differences between polar and equatorial temperatures influence the power and strength of depressions. Weather systems help ‘
normalise these differences’. At the time of the depression there was a strong temperature gradient across the Atlantic.
Unusually for this depression it began further south than normal, therefore it was fed by warm and moist air from the Caribbean. Slide4
