Weather Patterns and Severe Storms

Weather patterns appear evident by observing the weather for a number of years. Thus, in places in the middle latitude like the British Isles, northern Europe, and central North America, the summers are characterized by warm weather, the winters are cold accompanied by snow and ice, and the amount of rainfall in the months of June and November are quite the same. All these patterns of weather observable in a region for a number of years make up its climate. The weather has various elements but the most important are mean temperature and mean rainfall or precipitation. The others are wind, air pressure, humidity, cloud, and sunshine. The single source of power and energy that powers weather is the sun as it provides the necessary heat to kick off the different elements of weather (Jennings amp. Rosewarne 6-7).
Temperature. Temperature is the hotness or the coldness of the earth’s atmosphere and it is normally measured by degrees Celsius (Centigrade). This factor is important because it has a bearing on the other elements of weather. Temperature is affected by such factors as sunshine, time, geography and wind. Exposure to sunshine is determined by the length with which a
location is exposed to the sun’s intensity and the presence or absence of clouds. Time also affects temperature as the earth has varied exposure to sun due to earth rotation and revolution. Areas found in or near the equator have the least variation in temperature and the farther one goes from the equator, the higher the variation of the temperature. Other vital geographical factors are: altitude, or the distance from the sea level with the higher the altitude goes, the lower the temperature is. proximity to the sea, where temperature slowly changes. sea temperature, which varies from each other. currents of oceans, as currents that move towards the poles are warm while those that move water towards the equator are cool (BBC 2).
