Il clima in Inghilterra e in Italia

ENGLISH ENGLISH CLIMATE IN UNITED KINGDOM AND IN ITALY What is the climate? The climate is the whole of the normal and abnormal meteorology conditions that distinguish an area in a deliberate period (temperature, pressure, humidity, precipitation, winds,…). The makers that influence the climate are lots: the latitude (the distance, measured in degree, of a place from the Equator), the altitude (in normal conditions, in summer, the temperature decreases of 0,56°c for each 100 m but, in winter, the difference is, usually, lower), the nearness from the sea (the rainfall are higher and the thermal excursions are lower), from the rivers (in winter it's more wet and cold; in summer it's a bit less hot) and from the lakes (if it doesn't freeze in winter, the temperature is higher but, if it freeze, the temperature is more low). Moreover, another maker that influences the weather of a place, is the nearness of a mountain. In fact, it can reduce or decrease the quantity of precipitation or can make a place hotter or colder. The study of climate and weather is very important also to program what you can do during day and, more important thing, to foresee natural catastrophes and the trend of climate.  The climate in the United Kingdom In United Kingdom the climate is influenced by the movement of all the major air masses, including maritime tropical, maritime polar, maritime Arctic, continental polar and continental tropical. The UK, residing in the mid-lititudes, lies in the part of hair mass convergence between warm tropical airflow and cold polar airflow. At this convergence zone, the lighter warm air rises over the heavier cold air, producing the typical weather phenomena associated with this regime, fronts, depressions and rain. As a consequence, the UK climate is relatively mild for its altitude, since it is influenced by Gulf Stream. This stream is a warm ocean current that originates in the Gulf of Mexico and travels north-east across the Atlantic. For this reason Edinburg, for example, that is 56 degrees north of the equator, the same latitude of Moscow, have a climate much milder. Average wintertime surface temperature in Britain Although the British Isles makes up only a relatively geographical area, differences in climate across the region do exist. The climate of the western half of the British Isles is dominated by maritime tropical and polar air, whilst the east area climate is often influenced by more continental regimes. The climate of the United Kingdom can be divided into 4 quarters. The north-west quarter is characterised by mild winters (average 6°c) and cool summers (average 15°c), with, also, 2500 mm of precipitation per years. The north-east quarter has cold winter (average 3°c) and cool summer. Here the precipitation are lesser abundant but the snow arrives to plain. The south-west quarter experiences a more maritime climate during winter and warm summers (average 17°c). The south-east quarter have cold winters and warm sum
