Images of Europe (first attachment) and Ireland and UK (below) from space at midday. Colder air can be seen pushing across the North Sea into eastern Scotland and England![]() |

A nice illustration of the effect of a cold airmass overspreading a warmer North Sea surface in the presence of a sharp temperature inversion. The sharp temperature contrast between the sea and cold air causes vigorous convection in the boundary layer, which forms the cumulus streets. These rise until hitting the inversion, where they can rise no more, leading to this nice spotty pattern seen in the main picture. The hemispherical image shows the effects further upstream over eastern Europe, where much of the terrain is snow-covered. Notable is the cloud-free area west of Denmark, where the cold dry air has still not been modified enough by the sea to form clouds. This only happens after a certain distance, which is something I mentioned in the Cold Spell thread earlier. This effect may be problem for some east coast snow-lovers this week as the sea track over the Irish Sea from Wales may be too short for decent showers to form. It all depends on exact wind direction. |

Infrared image of Ireland and UK at 10:00 GMT this morning, showing another good example of the suppressed convection discussed above over North Sea and, to an lesser extent, the Irish Sea:![]() Edited by Patrick (IWO), February 1 2012, 02:11 PM.

The first image from MODIS features Ireland and the UK from space at midday today, 2 February 2012. Note the contrails created by aircraft over Ireland. Snow is also visible over the Pennines, parts of Wales and the Scottish Highlands. Also note the sediment around the Severn Estuary and Thames Estuary. In Feb/March, the Thames often carries sediment-laden water from the mainland into the North Sea, discoloring the blue water with tints of tan and sometimes green as the sediment sinks The second image (attached) from the University of Dundee/EUMETSAT shows western Europe at midday. Note snow cover over Denmark, parts of Central Europe and much of Eastern Europe and Russia.

Another satellite image of Ireland today:![]() Image source: Sat24.com Of note is bands of cumuli and stratocumulus clouds impinging along some southern and eastern coasts and moving generally from east to west; in contrast however, higher cirrus bands can be seen moving north to south over Ireland which are circulating in a clockwise direction around an upper ridge just off the west coast. This ridge is expected to decline a little over the next 24-36hr which will allow frontal zones to move in over Ireland from the west. |

Satellite image of Ireland taken at 1300hrs today. One of the more interesting features is the high band of cirrus that extends eastwards from weak frontal zones lying over the west of Ireland. ![]() Image Source: EUMETSAT |

Another one Mark. Meteosat 9 Visible at 1pm today. Cloud over Ireland is associated with weak but slow moving frontal zones which have basically parked themselves over the country. We should see these frontal troughs weakening further over the course of the weekend. Image Source: EUMETSAT |

Nice image there. What's interesting is the haar fog in The Wash, where cold air off the land moves out over the water in the light southwesterly breeze, forming stratus and fog. Here's the synoptic setup at 3 pm, courtesy of the Dutch Met (KNMI). The ridge axis lies just south of The Wash, so air will be flowing from a southwesterly to westerly direction north of the axis. ![]() |

A nice example of mountain waves down through much of the western UK and Ireland. |

Visible satellite of Ireland:![]() A scattering of showers can be seen over the country with more organised showery troughs moving southwards into Ulster. These showers will be mostly of rain or sleet but snow at lower levels cannot be ruled out as we head into this evening. Slight risk of thunder also. |
