temperatures continue to rise this week, with plenty of warm, dry and sunny weather expected across the UK over the Bank Holiday weekend. Met Office Chief Meteorologist, Frank Saunders, said: "We’ve already seen higher than average temperatures this week, with 19.4 Celsius reached yesterday (Wednesday 17th

breezes can help form convergence lines. These breezes develop as the land heats up during the day, causing the air above it to expand and rise, which ultimately draws in cooler air from the sea. If these onshore breezes meet opposing winds, a convergence line can form near the coast. Peninsular

In-depth analysis of the Arctic sea ice summer minimum and Antarctic sea ice winter maximum extent for 2019

). As measured by temperatures at 925mb (about 750m above sea level), the May-August period was the warmest on record over the Arctic Ocean, at 2.3°C above the 1981-2010 average according to the NCEP reanalysis (Figure 4). Some regions of the Central Arctic saw temperatures that were, on average, more

to be over hot temperature regime with 2.8°C in A2 and 2.03°C in B2 scenarios. Moreover, maximum annual temperature rise was computed in northwestern and west-central parts of Iran with 5- 6°C in A2 scenario. Beaches of the Caspian Sea, Persian Gulf, and Oman Sea would experience minimum annual

, where it was similar to that recorded in 2012 when the record-low September extent occurred. However, extent was nearer average, and well above the level of 2012, in the Laptev, Kara and Barents Seas on the Atlantic Ocean side of the Arctic (Figure 2). Figure 2.

of the Arctic, with mean sea level pressure lower than average everywhere except in the East Siberian Sea (Figure 4a). The Laptev Sea saw the highest temperature anomalies (Figure 4b), with a small region exceeding +3°C relative to the 1981-2010 average, partly due to very warm conditions from late June

from tropical oceans with sea surface temperatures normally in the region of, or in excess, of 27 °C; winds near the ocean surface blowing from different directions converging and causing air to rise and storm clouds to form; winds which do not vary greatly with height - known as low wind shear

. This is an area similar to the Fens, which lies just above sea level and in the past was subject to flooding. To the south of Bristol lie the Mendip Hills, which is an area of limestone rocks. The porous nature of the limestone has lead to a lack of surface streams with most drainage underground. Extensive
