for projects to learn from each other and work together towards the bigger picture of WISER Africa, rather than as discrete projects. The review meetings will also help projects prepare for Strategy Testing (see above) by supporting project teams to approach their MEL work with a more critical mindset

. Meteorologists use multiple computer simulations to account for chaos theory, the idea that small changes at the start of a forecast can lead to big differences by the end. At first, the Met Office and European models agree on the low’s position, but as Thursday progresses, their tracks diverge. The Met

Weather | Amazing aurora Activity steps But space weather forecasts are not only important for aurora-watching. When the solar wind is really strong, the charged particles can also interact with all sorts of technology, both here on Earth and out in space (slide 11). A big space weather event can cause

of something special for you’. I was so nervous that I didn’t look beyond the instrument panel at first, so completely missed the ‘big moment’ we became airborne, only realising we were up as we suddenly banked to the left and I found myself staring down a wing now pointing at a line of cars a few hundred

is really strong, the charged particles can also interact with all sorts of technology, both here on Earth and out in space (slide 11). A big space weather event can cause power cuts, it can stop satellites working and it can knock-out many types of communications. This is why it’s really important

lead to big differences in the weather we experience on the ground. In recent weeks, the jet stream has been either directed towards the UK, or shifted further south, which has predominantly brought cooler air over the UK, with frequent incursions of some unseasonable winds and rain. “For warm weather
