• You will be able to describe the passage of depression Klaus over the 23rd 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.

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.
