Powering up the forecasts East Africa has distinct wet and dry seasons, and accurately predicting the onset of its rains is vital for farms and businesses. Yet hydropower is equally reliant on accurate and timely forecasts – as an important climate partnership project recently demonstrated

1, is produced by combining output from the Met Office GloSea5 dynamical forecast system with statistical predictions based on pre-season sea surface temperatures (SSTs) in the tropical Atlantic and Pacific. The methodology is described in Part 2. The GloSea5 contribution to this forecast for FMAM

is gained. A climate of a particular place is often described in seasonal periods (e.g. summer/ winter or rainy/ dry season) over the cycle of the year. The climate can also naturally vary between different years due to the process of Earth system cycles, especially those associated with large

? Pollen production is heavily influenced by weather conditions. A warm and wet spring can lead to higher pollen production, while dry and breezy conditions help disperse it into the air. Conversely, a cold winter can delay the start of the pollen season by keeping plants dormant longer. Spring

to the surface the issues around communicating a ‘deterministic’ forecast. Many extension officers simply communicated that the season would be ‘wet’ and therefore the farmers should invest in crops. One particular group misunderstood the forecast, and farmers interpreted the 40% chance of ‘wet’ as being a 60

that falls in these seasons. In summer, convection caused by solar surface heating sometimes forms shower clouds and a large proportion of rain falls from showers and thunderstorms then. A further factor that greatly affects the rainfall distribution is altitude. Moist air that is forced to ascend hills

distribution to air frost. However, those places into which cold air can drain are particularly prone to frost. Examples include Altnaharra (Highland) with an average of 73 air frosts per year. In Northern Scotland the frost-free season is o en as little as 3 months, as shown by the average

member of RCM-PPE that gives lower PSS values though). This is consistent with the large (and significant) cold and wet biases seen in the north of the UK in this model in this season (Figures 16 and 18). The nested CPM-MRI reduces the contribution to the total rainfall from days with high rainfall
