) which we can drive around the screen with Driving the van to the volcano clouds on the right will collect the data (information). We can see where we have collected data as the boxes will have a border – red for dangerous concentrations of ash and blue for not dangerous. There is a score in the top

around Europe. These sensors make it possible to pinpoint the location of the lightning. A lightning discharge may be a lightning strike, in which lightning passes between a cloud and the ground, or the passage of lightning between clouds but not to the ground. The map shows the location

between a cloud and the ground, or the passage of lightning between clouds but not to the ground. The map shows the location and the frequency of the lightning discharges over the previous 55 minutes. The scale uses graduated colours to show the length of time from the strike. A yellow circle

a little: • Embedded (EMBD) cumulonimbus clouds will no longer be included which means that there will not be any areas of “ISOL EMBD CB”, Only OCNL and FRQ amounts of cumulonimbus will be shown. • Tropopause will be shown as contours (as a thin dashed line) instead of spot heights. • CAT areas

, possibly with embedded thunderstorms, across some southwestern parts. These will gradually break up into showers, persisting for much of the day. Most other regions will see variable cloud and a scattering of mainly light showers, with the chance of a moderate shower near southern coasts. Cloud and patchy

on Saturday. “That high sticks around on Sunday for the big race but it starts to edge back a bit further west which means there will be a bit of a northerly breeze in the southeast and quite a bit of cloud around as well.” Temperatures are likely to be around 6°C in Greenwich at the start of the day

in a number of different ways including from satellite data, by radar and by LiDAR (Light Detection and Ranging). The Met Office uses an instrument called LiDAR to measure ash clouds. LiDAR works by sending pulses of laser light through the atmosphere, which is scattered by volcanic ash particles. Some
