Climate and Polar Maritime Air Essay

To what conclusion is the modality of the British Isles a increase of the atmospheric state mountain that touch it? humour is defined as the hold out sightlyd oer a 30 grade period, with weather being determined by temperature, humidness, intrude and precipitation. The modality in the British Isles is depict as cool temperate horse opera maritime modality, although in that location be regional differences in humour across the British Isles with average temperatures ranging from -0.2 to 20.9 degrees Celsius. The clime of the British Isles is influenced by the movement of five major oxygenise mickle. However, it is withal influenced by other chemical elements, including its topography, naval currents, latitude, and weather systems. Firstly, it batch be argued that phone line stack race a erect part in the boilers suit mood of the British Isles. Air rabble be pear-shaped bodies of line of descent with reasonablenessably akin temperature, pressure an d humidity throughout. There argon five main give vent passel that influence the climate tropical maritime(TM), diametric maritime (PM), tropical continental (TC), opposite continental (PC) and arctic maritime (AM). The perpetration of the line of credit mickle can be analyzen in the diagram below. tropic naval tot ups warm wet pass round from the Atlantic Ocean.This warm mental strain hits reachs of last resi collectable in western England and Wales, causing the origin to rise, which believes clouds form. Areas of spicy relief in the west of England include Dartmoor and Exmoor. The manner is precise moist as it is from the ocean, so on that point is lots of precipitation. This wind is warm, which agency that is has a warming venture in the passtime, all the same in the Summer because the land has a light specific heat capacity, it heats up much than the Atlantic ocean. thus it has a cooling advert in summer. Tropical Continental duck soup masses br ing hot and dry line of merchandise in summer. This causes high temperatures with real little precipitation, and is the reason for heat waves in the British Isles. For suit the heat wave in July 2013, where temperatures reached 33.5C . Polar maritime oxygenize masses bring ice-cold moist winds as they originate from a north westbound direction, oer the Atlantic Ocean.This therefore causes real cold wet weather in the British Isles, especially in the westerly parts of the British Isles where there is high relief causing precipitation. Polar Maritime air is plethoric anyplace the winter season. Polar Continental air masses originate from high latitudes such as Siberia so therefore bring very cold conditions with them, however as they come out from land not ocean, the air masses bring dry conditions. diametric airmasses originate all over the Arctic Ocean where high pressure dominates.The air masses bring extremely cold temperatures, however is only dominant in winter, and fewtimes in spring. However this air mass is more likely to affect the climate in Scotland, and northern England, as it has come from a northernly direction. boilersuit this shows that air masses do play a world-shattering purpose in the overall climate of the British Isles, however almost air masses are more dominant than others in different seasons, and some air masses are dominant in different areas of the British Isles.The climate of the British Isles is in like manner greatly modify by weather systems such as embossments. Mid Latitude depressions are form over the Atlantic Ocean on the Polar lie. They move in an eastern direction across the British Isles. The depressions are low pressure systems that are organize when moist, warm air meets drier, colder PM air. The warm, moist air is hale upwards, by the colder denser air. The Coriolis make causes the air to rotate in an sinistral direction. The jet stream is similarly snarly as it moves the depression fro m west to east. The climate associated with depressions is strong winds, clouds and precipitation. However the climate is dependant on which air mass is over the British Isles. Polar maritime air brings average temperatures for the season in winter, roughly 5C-8C in January, precisely cooler temperatures for the summer season, at around 16C to 18C in July. This air mass also brings lots of precipitation.Tropical maritime air brings humid and mild weather in winter, with temperatures averaging at around 12C-14C in January. Tropical maritime can also bring thunderstorms , due to the humidity and low pressure. An simulation of when a depression has greatly affected the British Isles was the smashing Storm in 1987. This fast paltry depression caused wind speeds of up to 81mph. The British Isles possessd lots of rain fall down, and there was tied(p) an increase in temperature by 6C in places, where the warm front was situated. This shows how depressions can have great impacts on the climate of the British Isles, however this tumescent depression is not common, so does not usually affect the climate. Overall, depressions have a great impact on the climate of the British Isles both in winter and summer, however it can be argued that air masses play an important role in the system of depressions, so this also shows that air masses indirectly affect the climate.The BritishIsles has a latitude between 50N and 60N. This has a great impact on the climate that it experiences, importee that the latitude is another(prenominal) factor that get out influence the climate of the British Isles. The latitude of an area will affect how much thermic fever it will receive. This is due to the angle of relative relative incidence, which can be see in the diagram below. A big angle of incidence will mean that the thermic fever from the sun will only disperse over a beautiful area, whereas a small angle of incidence means the same amount of insolation will be spread ove r a larger area. At a 30 angle, a one device wide ray of insolation will be dispersed over a two mile radius, whereas an angle of incidence of 90 with the same ray of insolation will be dispersed over a one mile radius. high latitude have smaller angles of incidence, meaning that they will receive less insolation. thence the latitude of the British Isles means that there will be temperate conditions. It is not likely that the British Isles will experience a very hot climate due to the fact that id does not receive enough insolation to heat up the surrounding air and ground. This can be seen if you compare the average yearly temperatures of the British Isles compared to Somalia, which is found at a get down latitude of 2.03. The British Isles has an average temperatures ranging from 8.5-11C. In contrast Somalia has temperatures around 24-31C. This demonstrates how that latitude of an area can greatly impact the temperature, which means it affects the overall climate of the area. T his shows that latitude is a factor other than air masses that will impact the climate of the British Isles.Altitude is another factor that influences the climate of the British Isles. On average the air temperature falls by 0.65C every 100m rise in elevated. This is due to the fall in pressure as the altitude increases, meaning molecules have less energising energy. For example Ben Nevis has a height f 1,344 metres, and has an average annual temperatures of -5C, compared to the British Isles which has an average annual temperature of around 8.5-11C. This shows that altitude has a direct impact on the temperature of the British Isles, so areas of high altitude in the west of the British Isles, such as Cambrian will have lower temperatures.The altitude of the British Isles will also cause precipitation, as when moist air masses move across areas of high relief, the air masses are forced upwards, where thecool condense and form clouds. For example in Wales the Cambrian mountains rec eive over 100mm rainfall per month all year round. This is due to the tropical maritime and diametral maritime winds bringing moist air. Overall this shows that altitude can have a large impact on the climate of the British Isles, however air masses are also refer in this, which demonstrates that air masses still play a significant role in the overall climate. Lastly, ocean currents are another factor that have a large impact on the climate of the British Isles. The most significant ocean current is the Gulf Stream, which . Gulf Streams are influencedIn conclusion, the climate of the British Isles is a yield of air masses so a large extent. Although there are numerous other factors that also affect the climate, air masses are also involved in these factors, such as the formation of depressions, or the movement of ocean currents. Therefore air masses so also indirectly influence the climate of the British Isles, meaning that they play the most significant role in affecting the cl imate.
