regions, especially in the northern part of the continent, weather conditions can change rapidly and a short dry spell can still lead to high fire activity even during a wetter than average season - please see Figure 8a showing fire trends and accumulated hot pixels in the Technical Information section

of annual indices have also been calculated and gridded. These were derived from daily temperature (T) or precipitation data using the following definitions: • Growing Season Length (GSL) = period (days) bounded by daily T_mean > 5 °C and < 5 °C (after 1 st July) for ≥ 6 days. • Heating Degree Days

is important, here we only present seasonal mean quantities for the June to August (JJA) season, the most active season for TCs in the WNP; the Technical Report shows the results for all seasons. This analysis serves as a starting point to help build physical understanding to underpin analysis

that is used to measure the air pressure around us. Pressure is important as it can tell us about what kind of weather to expect; when the pressure is high, we can usually expect clear skies and light winds, when the pressure is low we can usually expect wet and windy weather.

2020 also exceeds the sunshine amount for most summer seasons, with only three summers being sunnier (1976, 1995, and 1989). The figure for England is even higher. Spring 2020 recorded 696 hours of sunshine, exceeding the previous record set of 594.3 hours All UK countries have recorded their sunniest

Storm Dennis Storm Dennis was the fourth named storm of the 2019/2020 season. Arriving one week after storm Ciara, Dennis brought heavy and persistent rain across much of the UK – especially Wales and western England. Western upland parts of the UK received 50 to 100mm or more of rain falling

in the south Asian summer monsoon and in parts of the extratropical North Atlantic Ocean, with wet biases over the Indonesian warm pool. In the Indian ocean sector, wet biases occur off the coast of Madagascar in DJF (in the region associated with the southern lobe of the Indian Ocean dipole (Behera

decades. • Over land the projected general trends of climate changes in the 21 st century are similar to UKCP09, with a move towards warmer, wetter winters and hotter, drier summers. However, natural variations mean that some cold winters, some dry winters, some cool summers and some wet summers

to the west creates an environment that is frequently cool, dull and wet. However, the Pennines can cause the cloud to break up downwind, meaning warmer days but cooler nights. If low winter temperatures coincide with high winter precipitation, heavy winter snowfall may occur across Kirklees. Snowfall

experiences more cloudy, wet and windy weather than regions further east. Some upland areas experience harsh weather whilst coastal and lower lying areas enjoy more favourable conditions. Winter mean daily minimum temperatures vary from 0°C in high parts of north and mid-Wales to 3 or 4°C around the coast
