occur high in the atmosphere, typically between 80 and 300 kilometres above the Earth’s surface. To see them, clear, dark skies are essential. Even thin cloud can obscure the subtle colours and movements of the aurora, while thick cloud makes sightings impossible. Light pollution from urban areas

will give way to increasing cloud cover. Some patchy light rain is possible, especially in western Scotland and Northern Ireland. Temperatures here will be notably cooler under the cloud, particularly in central and western parts. Will any temperature records be broken this week? 🌡️ Here's our

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

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

in southern Australia.  In light of the Australian fires, in January 2020 an international group of scientists, including from University of East Anglia (UEA), Met Office Hadley Centre, University of Exeter, Imperial College London, and CSIRO Oceans and Atmosphere reviewed published scientific evidence

- many should see a decent amount of sunshine. “With the exception of the southeast at first, where it will be rather cool to start the weekend, temperatures are generally unremarkable for the time of year, close to or a little above average. However, it will feel a little warmer with light winds

, where outbreaks of rain and drizzle are expected. Some rain may also affect parts of Wales and the southwest for a time. Elsewhere, cloud cover will be more variable, with a few isolated showers breaking out later in the day. While most of these will be light, there is a low risk that some could

settled conditions across much of the UK, with most areas enjoying dry weather and sunny spells. Temperatures will be close to the seasonal average, though it will feel pleasantly warm in the sunshine, especially where winds remain light. Eastern and southeastern England may see more in the way of cloud

Thursday will begin with some early fog patches across western areas, but these will soon lift to leave a largely sunny day across much of England and Wales. Further north, Northern Ireland and particularly Scotland will see more in the way of cloud, with outbreaks of mainly light rain and drizzle
