and are almost guaranteed to cause fatalities in such incidents. Thunderstorms also cause death and injury from lightning strikes and occasionally from hail stones. Indeed, Uganda has one of the highest reported rate of lightning strikes in the world 158 - 218 per square km (see Powell, 2016). Mary

The hot weather will continue across the UK, with heatwave conditions for many, creating ideal conditions for thunderstorms which will bring heavy rain and increasing risks from flash flooding, lightning and hail..

learned previously, precipitation is water that falls to the ground and includes rain, snow and hail. Encourage the children to compare these two projections. • Prompt questions: In which scenario (high or low emissions) is there greater precipitation, meaning that it is wetter? Are there any

of raindrops. In turn, understanding more about their structure will help forecasters accurately pinpoint the difference between rain, hail and snow. And that means they can provide clearer and more accurate information about heavy rainfall – especially during high-impact weather. Clearing the way

densities and fall speeds than snow. Graupel is typically smaller than hail and forms when supercooled water coats a snowflake. Subsequent testing has shown that the UKCP Local (2.2km) projections (including for temperature, precipitation and wind) can still provide important information for many

the area of the sample, and a funnel that channels the collected rain into a measuring mechanism or into a reservoir where it may be measured at a later time. As the name implies, rain gauges measure rain not snow, hail or other forms of frozen precipitation. The entrance to the gauge through

gauges measure rain not snow, hail or other forms of frozen precipitation. The entrance to the gauge through the funnel is narrow to avoid debris clogging the mechanism and undesirable evaporation in hot weather. However, the gauge rapidly becomes blocked in snow and any readings at the time

(and proxies) for hail, lightning, wind storms, fire weather, etc. • Focus on data sets of extremes for the UK (both climate extremes and high impact weather events) and UK-responsibility observations back to 1800 and stimulate and coordinate rescue of historical data to improve such data sets • Develop new
