associated with the typical low pressure and frontal systems that cross the UK to be recorded. Some weather features occur on smaller scales (for example thunderstorms) and may evade the surface network altogether. For the detection of these satellites and weather radars play an important role
the first week of May led to surface water flooding in Aberdeenshire, Leeds and Bradford. Settled weather moved in from the 7th as a high pressure centre took up residence close to the UK. Clear weather across the UK coincided with a major geomagnetic disturbance which led to widespread sightings

Sea breeze - As we saw in session 1, wind comes from the movement of air from high pressure to low pressure regions. In the summer, the surface of the land is heated by the sun and becomes hotter than the surface of the sea. This causes the air above the land to rise (also convection taking place
pressure, or depression, at the surface. There are various trigger mechanisms required to transform these cloud clusters into a tropical cyclone. These trigger mechanisms depend on several conditions being 'right' at the same time. The most influential factors are: a source of warm, moist air derived

between the 9th and the 25th; the UK's warmest June on record. • Periods of thunderstorms, heavy rain and flooding. After an uneventful spell of settled, anticyclonic conditions, high pressure moved away and warmer, more humid air arrived which gave rise to rainfall and thunderstorms for some areas
from the south-west, with widespread falls of rain between the 4th and the 11th. Heavy thunderstorms and locally torrential rain caused flooding in many southern and eastern areas of England on the 9th. Towards mid-month things settled down, with high pressure building, and from the 12th onwards any
