The FSR includes values for two key variables mapped across the UK: the M5-60 minutes rainfall, and the ratio "r". M5-60 minutes rainfall is the expected depth of rainfall in millimetres (mm) from a storm lasting 60 minutes (1 hour) with a return period of 5 years (hence M5). M5-2 days rainfall is the expected depth of rainfall from a storm ...
Rainfall intensity, the amount of water likely to generated in a two-minute rainstorm is more important than average rainfall, the British Standards Institute [14] notes that an indicative storm in Essex, (annual rainfall 500 mm per annum) delivers 0.022 L/s/m²- while one in Cumbria (annual rainfall 1800 mm per annum) delivers 0.014 L/s/m².

A typical installation of insulated glass windows with uPVC frames. Possibly the earliest use of double glazing was in Siberia, where it was observed by Henry Seebohm in 1877 as an established necessity in the Yeniseysk area where the bitterly cold winter temperatures regularly fall below -50° C, indicating how the concept may have started: [2]

Monsoons are large-scale sea breezes which occur when the temperature on land is significantly warmer or cooler than the temperature of the ocean. Most summer monsoons or southwest monsoons (Filipino: Habagat) have a dominant westerly component and a strong tendency to ascend and produce copious amounts of rain (because of the condensation of water vapor in the rising air).
