MetLink Activity 7

Please note that the study format used in this can be applied to areas of the world other than the Europe by using the MetLink resources listed at the end of the activity.

Weather around Europe on Tuesday 31 January 2006:

This activity is designed for use with students aged 14 to16 years. In England and Wales, these are GCSE students; in Scotland they are young people studying for Standard Grades.

The aims of this activity are:

+ to use IT skills in finding information.
+ to use mapping and graphical skills in presenting information, making use of standard weather mapping symbols.
+ to describe weather conditions and how they vary in different locations.
+ to interrelate and attempt to explain weather conditions.

The Activity:

You need the following:

1. Large outline map of Europe.
2. Atlas. If you have access to Microsoft Encarta that would be good. Or you can use an atlas book.

1. Go to the MetLink observations database by using the MetLink Home page

+ click on Data central

+ click on Search observations

+ make sure the dates are set correctly

+ click on Search now

This shows you all of the observations made by MetLink participants for the day.

1. Select MetLink participants from Europe who have logged data so far. They are in: CY Cyprus; ES Spain; FR France; IT Italy; MT Malta; RO Romania; SE Sweden; SK Slovakia. Also select three participants from the UK – one from south-e ast England, one from Wales and one from Scotland.
2. Plot the data for each location using the standard Met Office key which you can obtain by clicking here. For temperature, use both the maximum and minimum values. For cloud types, use the following letters: H for high level clouds; M for medium level clouds; L for low level clouds; V for clouds of great vertical extent.

High-level clouds: Ci Cirrus; Cc Cirrocumulus; Cs Cirrostratus
Medium-level clouds: Ac Altocumulus; As Altostratus
Low-level clouds: Cu Cumulus; Sc Stratocumulus; St Stratus
Clouds of considerable vertical extent: Ns Nimbostratus; Cb Cumulonimbus.

2. Using your map, describe the pattern of weather across the UK today using the following subheadings:

a. Temperature
b. Precipitation
c. Wind direction and force
d. Cloud amount and type

3. Study the satellite images of Europe. Click here for the 06:00UTC infra-red image and click here for the 12:00UTC visible image. Remember that on the infra-red image cold cloud which is at high altitude appears white. If it is a rather “thin” white, then this indicates it is only a high-level cloud such as cirrus. If it is a very intense white this means the tops are at high altitude, but there is a considerable vertical extent of cloud below. Low cloud is much warmer and appears grey on the IR image.

a. Describe the pattern of cloud distribution and type.

b. Comment on how it compares with your answer to 2d above.

4. Now explain how the cloud distribution you have described is related to the position of high- and low-pressure systems (anticyclones and depressions) and the positions of fronts by studying the Europe weather chart 12:00UTC (click here).
