High pressure will influence the UK’s weather this weekend, but what does that mean for the thousands of people running the TCS London Marathon?

Office Meteorologist and Presenter Alex Deakin said: “If you’ve been training hard for the London Marathon, you’ve probably been training in the rain and under the influence of low pressure. Our weather patterns are shifting this weekend and high pressure moving in will bring many of us a fine day

“In a recent study we found that the likelihood of extremely hot days in the UK has been increasing and will continue to do so during the course of the century, with the most extreme temperatures expected to be observed in the southeast of England.  “Climate change has already influenced the likelihood

Space weather refers to the environmental conditions in space as influenced by the Sun and the solar wind. Unlike Earth’s weather, which involves water, air, and temperature, space weather

In September, as the sun starts to set over the Arctic, the annual cycle of summer sea ice melting draws to a close. As the influence of the Sun's rays decreases, the ocean surface cools, the sea begins to freeze once again and the sea ice cover expands. When quantifying the amount of sea ice

Pollution from cars and factories is a major source of man-made aerosols but they can also be produced naturally

By 2070, the chance of exceeding 30°C for two days or more throughout the year increases. Projections show that over southern parts of the UK exceeding 30°C for two days or more becomes
