  ...The Great Storm of 1987 By Scarlett The British Isles weather patterns Air masses and the British weather. The five major air masses which affect the British Isles (Arctic maritime, Polar continental, Tropical continental, Tropical maritime and Polar maritime) are which contribute to the weather in the UK. When the air masses mover from their source region they change and are modified from the surface over which they travel, this alters there temperature, humidity and stability. For example, tropical air moving northward is cooled and becomes more stable, while polar air moving south become warmer and increasingly unstable. Each air mass brings its own characteristic weather conditions to the British Isles. When two air masses meet, they do not mix readily, due to differences in temperature and density. The point at which they meet is called a front. There are two different fronts: warm and cold front. Warm fronts are found where warm air is advancing and is forced to override cold air. A cold front occurs when advancing cold air undercuts a body of warm air. The warm air is forced to raise, cool and condense producing rain clouds. The clouds are often followed by precipitation. This is a weather system known as a depression. A depression is what occurred over the south west of England during October 1987. Depression is an area of low pressure. It causes unsettled weather, most famously clouds and precipitation. This is due to the centre of the...

  ...Geog task 51 – exam question Discuss the impacts of storm events in the British Isles and evaluate the responses to them (40 marks) ------------------------------------------------- ------------------------------------------------- ------------------------------------------------- The British Isles has a cool temperate western maritime climate including four seasons and various weather conditions. Storms come and go some so weak they are unnoticed and some bring in heavy winds and torrential rain and thunder. Depressions are areas of low atmospheric pressure which produce cloudy, rainy and windy weather. These low-pressure systems often begin in the Atlantic, moving eastwards towards the UK. They are responsible for the UK's changeable weather. A storm event we will look at in the British Isles happened in 1987. The storm struck the South West & South East of England which devastated buildings and left 12 people dead. This global location is prone to depressions. The storm was initially directed towards northern France and Europe but veered up to the U.K. The sea water from the surrounding ocean flooded people’s homes causing people to flee their homes and evacuate. This cost England thousands of pounds including insurance claims. The surrounding tide from the sea was said to have raised by around 2 to 3 meters. Approximately 40 mm of rain and hail fell in the course of a few hours. The main cause of deaths was mainly from flooding and high wind speeds –...

  ...The Cold War started around the time of the end of World WarII (1945) and went on until the fall of the Berlin Wall in 1991. Karl Marx, a German revolutionary, was critical of the societies of Europe and the US. He believed because they were dominated by capitalism, that they werenʼt for the masses, but for the individual. Well, thatʼs what communism is based on, but corruption has a way of bleeding in. Stalin and WWII Under Stalinʼs rule, the Soviets diverted resources to their military and away from the much needed economic and social development of the Russian people. They promoted communism by military coercion. After WWII, Stalin had created allied communist states and went into Eastern Europe. Churchill and Roosevelt ceded control of Central Europe to Russia because they were busy reconstructing the postwar economies of the rest of the area. Even though they were two different ideologies, they had a common enemy-Nazi Germany. Eisenhower let the Soviet Red army go into Berlin first, which gave them a foot-hold on the area. US and itsʼ allies organized to stop the Soviets from extending their power even further, and perhaps elsewhere. So in 1950-60, the “Iron Curtain” was named when it became clear to allied leaders that Russia was to dominate Central Europe. Eastern Germans were dissatisfied with communist life and started fleeing to West Germany even though it had been surrounded by barbed wire. In 1961, Soviet leader Khrushchev, built the Berlin Wall...

  ...with a long land or continental track will remain dry. Fig 2: Modification of air mass by land and ocean surfacesA cold air mass flowing away from its source region over a warmer surface will be warmed from below making the air more unstable in the lowest layers. A warm air mass moving over a cooler surface is cooled from below and becomes stable in the lowest layers. Fig 3: Modification of air mass due to surface temperatureIf we look at the temperature profiles of the previous example, the effects of warming and cooling on the respective air masses are very different.Fig 4: Modified vertical temperature profiles (----- line) typical of: a) tropical air cooled from below and b) polar air heated from below on its way to the British Isles. Note that where the air is heated from below the effect is spread to a greater depth of the atmosphere.

There are four main types of air mass. * Tropical continental (Tc) * Tropical maritime (Tm) * Polar continental (Pc) * Polar maritime (Pm)And two further sub-divisions. * Arctic maritime (Am) * Returning polar maritime (rPm)Each of these air-mass types has its own distinctive combination of properties in terms of: * temperature; * moisture content (relative humidity); * change of lapse rate; * stability; * weather; * visibility.2.1 Tropical continentalTropical continental air affects the British Isles predominantly during the summer....
