in tropical cyclones using Regional Climate Model experiments Tropical cyclone activity in the Philippines A tropical cyclone (TC) is a persistent synoptic-scale low pressure system originating over warm waters, with organised convection and a mean windspeed of at least 17.5m/s (39mph); it is a “typhoon

at or in the vicinity of the airfield during the defined period. A warning stating that ‘Thunderstorms are likely to affect the airfield at times’ should be used to infer that there is at least a 40% probability for a thunderstorm to occur at or in the vicinity of the airfield during the defined

to see temperatures in excess of 30°C in June – we can expect to see at least one day where a temperature of over 30 °C is recorded in three years out of ten. The last time we saw temperatures exceed 30 degrees in June was 30th June 2015 when temperatures reached 30.5 at Northolt, London during

down in the mid-single figures for the south and east. So, a fairly cool feeling day. “As we head towards Sunday, there is unfortunately further wet and windy weather to come. Through the evening though, it'll likely stay fairly dry, at least across more northern areas. The rain will slowly start

and help reduce the impacts from the hazards that severe convection generates. 4) Science for Services: this activity could provide a foundation for the development of prototype services that deal specifically around the hazards severe convection produce. To achieve this activity, at least 1 FTE would be required per year, though to get the maximum value 2.5FTE over 3 years would be more appropriate.

. The government is committed to increasing levels of research and development (R&D) to at least 2.4% of GDP by 2027. In the autumn, the government will set out plans to significantly boost public R&D funding, provide greater long-term certainty to the scientific community, and accelerate its ambition
