Due to the water body’s thermal capacity, this warming process takes longer, than that of the surrounding lands, thus providing a cooling effect during summer time. Moreover, the presence of winds, which bring air from the ocean body; spreading out over the Isles is noticeable. The result is definitely the presence of rain, though there is either a warming or a cooling effect present.Different regions of the greater British Isles do experience a contrast in terms of prevailing temperature and weather conditions. This is showcased by the fact that despite the prevailing weather conditions i. winter or summer it is colder in the north, as compared to the south of the Isles. In addition to this is the fact that the western region is generally warmer than the west. This includes the coastline of Western Scotland and England, as well as Wales and Ireland (Rayner, 1981:18). The latitude of the region further influences existing climatic conditions, with the southern areas receiving more isolation than the northern areas. This is in terms of the sun’s angle, in relation to the Earth’s tilt on its axis.Altitude matters, in terms of sea-level placement of land. The British Isles, Wales is placed on higher ground, with colder temperatures being experienced. There is influence by the average temperature fall of 0.65o Celsius for every 100 meters of altitude gained. Lesser insolation – incoming solar radiation absorbed by earth – provides a fall in temperature in relation to the prevailing air pressure levels. An increase in altitude results in a fall in air pressure, thereby affecting the rate of kinetic energy produced due to limited ability of air molecules colliding. Air masses and prevailing winds, in terms of impacts, also affect the Isles.If the prevailing winds is emanating from the north, this leads to colder temperatures vis-à-vis winds from the south influencing an increase in temperature. In the region, the dominant prevailing wind, referred to as the ‘westerlies’, do emanate from the Atlantic Ocean. They do increase the rate of evaporation through the journey, hence gathering huge quantities of water vapor. Warm air rises, in relation to the rise of altitude, resulting in a fall of air pressure. This catalyzes the formation of cloud cover, with rain drenching the Western region of the Isles (Parker, 1992:34).The Breccan Beacons (Wales), the rising
