of the Earth’s atmosphere and surface. Objects that reflect most light, such as cloud, appear whiter than objects that reflect less light, such as land. Thicker clouds appear whiter than thinner clouds. The scale on the legend indicates albedo (or reflectivity) on a scale from 0 to 1. Visible satellite

The intensive testbed with its main hub in Zambia and centres in Mozambique and South Africa, hit the ground running on 30 January 2025.

and nowcasts – sent every two hours. The morning’s forecasts predicted some heavy rainfall for Kanyama. While the team at ZMD experienced two brief but heavy showers during the morning, the Kanyama community observers reported that they experienced only light rain. This led to a discussion about how

totals are based on the average value across each county. Lead author and Met Office climate scientist, Mike Kendon, said: “Our new analysis of these observations really shines a light on the fastest changing aspects of our weather as a consequence of climate change. Long term averages can be difficult

extent lower than every year before 2007. Each year, scientific centres around the world submit predictions of September Arctic sea ice extent to the Sea Ice Outlook (SIO), a series of reports published in June, July and August by the Sea Ice Prediction Network (SIPN). The second report of the summer

on the ground, mounted on an aircraft or satellite-based, and can be used to observe the location and vertical profile of aerosols such as volcanic ash. A lidar measures backscattered light from atmospheric targets e.g. aerosols including volcanic ash and Saharan dust, water droplets and ice crystals, using

, and all results are for RCP8.5. The orange dots and light blue dots represent the sets of GC3.05 and CMIP5 projections respectively. Two example models selected from the set of 28 global projections are shown in red and dark blue. From figure 2.14 of Lowe et al (2018). How to use joint probability plots

. Otherwise, it will be a fine day with light winds and a fair amount of sunshine in many areas, although freezing fog patches could persist in a few places.  How long the more settled, colder conditions will last is uncertain, with rain probably returning to westernmost areas at least by the end of the week

, with cloud perhaps thick enough to bring patchy rain or drizzle. Winds will be light for most but will strengthen in the far northwest as the day progresses. High pressure’s back (briefly) 👀 - Warmer & more settled on Friday and Saturday ☀️ - Humidity climbs Saturday night💧 - Low pressure returns

difficulties. In 2022, the Trackplot team identified that environmental hazards and severe weather conditions were critical factors to monitor to keep outdoor workers safe, particularly in light of climate change impacts. Met Office predictions for 2070 compared to 1990 indicate that winters will be between 1

low cloud throughout the day. Winds will be light to moderate for most, although a strong and gusty easterly breeze is forecast across southwestern areas. This may bring a fresher feel to parts of Devon and Cornwall, despite the sunshine. Temperatures will again be very warm or hot in the west
