Beginners Guides:
A Cold Front Simulation (2 of 4)

12.00 10 February 2000
12:00 Thursday the 10th of February, and yes there was indeed a short burst of heavy rain as the cold front passed over. As it passed cloud cover increased steadily 8 oktas (cloud cover is measured in oktas so its easy to estimate by eye). 7mm of rain fell in just one hour (at 8:00 as everyone was coming into school!). As it approached, air temperature dropped by 3 degrees centigrade as the cold air replaced the warmer air.

On the Satellite map we can see as long band of cloud, clearly showing the position of the cold front now passing over the North Sea.
