词条 | Climate of London |
释义 |
London, the capital of England and largest city in the United Kingdom, has a temperate oceanic climate, with warm summers and cool winters. While the city annually has modest precipitation, there are long periods of overcast skies and frequent light mist-type precipitation, which may account for the rainy image of the city. Within the current boundaries of Greater London, the coldest temperature ever recorded was {{convert|-16.1|C}} at Northolt in January 1962, and the highest temperature ever recorded was {{convert|38.1|C}}, recorded at Kew Gardens during the European Heat Wave of 2003. London averages about 1600 hours of sunshine annually. London's large built-up area creates a microclimate (an "urban heat island"), with heat stored by the city's buildings. Sometimes temperatures are 5 °C (9 °F) warmer in the city than in the surrounding areas. The urban heat island effect creates a microclimate in inner London, as seen in the London weather centre climate table below which features a bordering humid subtropical climate (according to the Trewartha climate classification), compared to the other climate tables below with a cooler oceanic climate.
