. Radio waves emitted from a radar antenna travelled outwards at the speed of light, only bouncing back to the same antenna when they encountered an object. When the weather was clear, radar could quickly provide intelligence on the position of aircraft in the sky. When it was raining or snowing, echoes

and it was mostly cloudy in the north with some light rain on the 2nd and 4th, but central and southern areas remained dry and sunny with overnight frosts and some patchy fog, which was particularly widespread early on the 4th. East Malling (Kent) recorded 7.8 hours of bright sunshine on the 3rd. After

with some morning fog patches, and the south-west had some light rain. A band of rain spread southeastwards across the country on the 2nd and 3rd, with brighter weather and just isolated showers following behind to most areas on the 3rd. High pressure gave mostly dry and benign weather on the 4th

counties, while other areas away from eastern coasts were brighter. Patchy rain and drizzle in eastern parts on the 30th became more showery later; in western areas cloud broke up to allow warm sunshine, though enough cloud built up in the south-west during the afternoon for isolated light showers

with wavelengths just longer than red visible light but shorter than microwaves and radio waves (700-1500 nanometres). Infrared light is used for thermal imaging, but also to change the channel on your TV! Satellites (more on this in session 3) – Anything that orbits the earth! Specifically, earth imaging

The impacts of extreme rainfall could be more frequent and severe than had previously been thought at the last UN climate conference, COP25, two years ago in Madrid. A new generation of climate models and the latest IPCC assessment (AR6) have provided a new light to look at the recent catastrophic

This was deemed particularly important in light of the COVID- 19

from a few showers across North East Scotland it was generally dry across the United Kingdom with sunny spells, more particularly across southern areas. Winds were light across southern parts but a light to moderate, later fresh, west or south-westerly wind affected northern areas. Temperatures were
