Climate of Europe and western europe

Water is a better conductor of heat than land. Since Western Europe has more surface area in contact to water in summer it gets less hotter and in winter it has more moderate climate than Eastern Europe because the sea helps in radiating the heat and cold. The Sea in the West is more moderate in temprature so it helps the western Europe



Maritime.

Most of the western Europe and Great Britain has a Temperate or Mesothermal climate – what’s known as a type C climate. More specifically the region has a largely Oceanic or Maritime Temperate climate – type Cfb.

Am I having a deja-vu, I'm sure I just answered this same question

Climate of Europe

Biomes of Europe and surrounding regions:
     tundra      alpine tundra      taiga      montane forest
     temperate broadleaf forest      mediterranean forest      temperate steppe      dry steppe
The climate of Europe is of a temperate, continental nature, with a maritime climate prevailing on the western coasts and a Mediterranean climate in the south. The climate is strongly conditioned by the Gulf Stream, which keeps mild air over the high latitude northwestern region over the winter months, especially in Ireland, the UK and coastal Norway. Whilst Western Europe has an oceanic climate, Eastern Europe has a drier, continental climate. Parts of the Central European plains have a hybrid oceanic/continental climate. Four seasons occur in Eastern Europe, while southern Europe experiences distinct wet season and dry seasons, with prevailing hot and dry conditions during the summer months. The heaviest precipitation occurs downwind of water bodies due to the prevailing westerlies, with higher amounts also seen in the Alps. Tornadoes occur within Europe, with most but not all occurrences being weak. The Netherlands and United Kingdom experience a disproportionately high number of tornadic events.[citation needed]

Overview

Prevailing westerlies (which squeeze between the Icelandic Low and Azores High) bring rain from the Atlantic ocean, the position moves southward during winter and rises further north in summer. The Siberian High brings colder, drier weather from the east. Away from the sea, parts of Central and Eastern Europe have a borderline Oceanic/Continental Climate as they are milder than they would otherwise be due to the open ice-free waters of the North/Baltic Seas and lack of mountain barriers, but are not as mild as the Western coasts, and are subject to more frequent snowfalls. The Danube region through the Balkans, Ukraine and Southern Russia have a continental climate with cold winters and hotter summers, some areas bordering on a dry steppe climate with only certain months of higher precipitation, often due to thunderstorms. Some coastal regions of the Black Sea have microclimates that are borderline humid continental/humid subtroptropical (or sometimes just the latter) due to the winters being mild enough and summer precipitation being high enough to preclude them as being Mediterranean, for example in Sochi, Russia. On the plains of Northern European Russia up to the Ural Mountains, the winter climate is much harsher than elsewhere in Europe with many months of below freezing average temperatures but with periods of hot summer weather.

Gulf Stream

The climate is of Western Europe is milder in comparison to other areas of the same latitude around the globe due to the influence of the Gulf Stream. Mediterranean waters are not as deep as the large oceans, allowing it to become a heat store tempering winters along its coastlines.[1] The Gulf Stream is nicknamed "Europe's central heating", because it makes Europe's climate warmer and wetter than it would otherwise be. The North Atlantic Oscillation and Arctic Oscillation also play large roles in determining the amount of Arctic air that penetrates southward diminishing the Gulfstream's warming effects during winter. [2]
Comparing to other parts of the globe, the average temperature throughout the year in Naples is 16 °C (60.8 °F), while it is 13 °C (55.8 °F) in New York City, virtually the same latitude. Berlin, Germany; Calgary, Canada; and Irkutsk, in the Asian part of Russia, lie on around the same latitude; January temperatures in Berlin average around 8 °C (15 °F) higher than those in Calgary (although Calgary sits 1200m higher in altitude), and they are almost 22 °C (40 °F) higher than average temperatures in Irkutsk.[1] This difference is even larger on the northern part of the continent; the January average in Brønnøysund, Norway,[3] is almost 15 °C warmer than the January average in Nome, Alaska,[4] both towns are situated upwind on the west coast of the continents at 65°N, and as much as 42°C warmer than January average in Yakutsk which is actually slightly further south. Further south the oceanic climate of Europe compares thermally to North America, at around 48°N Rennes, France has about an equal average temperature throughout the year to Seattle, Washington, although the latter has drier summers with much wetter winters [5


Europe Climate
Of all of Europe’s advantages, none stand out as much as Europe’s mild and temperate climate [euclimat].  At first glance it would appear to be a harsh and cold climate, due to its northerly position on the globe [wwoutsm] (most of the continental land mass lies north of New York City).  But winters in Madrid and Paris are less severe than those in New York and Boston.  The reasons for Europe’s mild climate are due to two factors;  prevailing westerly winds and the North Atlantic Drift ocean current [euocncur].
Europe’s northerly location places it in the prevailing westerly wind belt.  This brings mild maritime air from the Atlantic modifying the winters and summers (Africa’s dry land mass lies just across the Mediterranean).  These prevailing winds also prevent bitterly cold arctic air from penetrating into the continent instead they sweep into Russia, which does experience bitterly cold winters.  Only occasionally, due to changes in jet stream currents, does arctic air penetrate all the way to the Mediterranean.  Instead of continental polar air masses, Europe is dominated by cool maritime air from the Atlantic.
Adding to the moderate climate, ocean temperatures are warmer than what would be expected at this location.  This is due to the North Atlantic Drift [euocncur]. This is a warm water ocean current, an extension of the Gulf Stream, that originates in the tropical Atlantic, Caribbean Sea, and the Gulf of Mexico.  As the current moves past Cape Hatteras, North Carolina, it moves northeastward towards the British Isles, Scandinavia, and even into the Arctic Ocean where the port of Murmansk [rufb] (This Russia port remains open in the winter, albeit with ice breaker help, despite being located above the Arctic Circle.)
The warm water (relatively speaking) of the North Atlantic Drift warms the air masses that invade Europe from the west and provides enough moisture and instability that gives much of Europe beneficial precipitation [eupreces].
These climatic controls help to explain Europe’s climate of not too many temperature extremes and adequate precipitation.  Most European climate [euclimat] falls under two classifications;  Marine West Coast (Cfb) and Mediterranean (Csa).
Marine West Coast climate is typically found along the west coasts of continents (typically between 40o and 60o latitude).  This climate covers much of Northwestern Europe including the British Isles, but excluding Scandinavia, Eastern Germany, Poland and Switzerland.
The other dominant climate in Europe is the Mediterranean (Csa, Csb).  This climate [euclimat] covers much of Southern Europe including most of the Iberian Peninsula [iberia], Southern France, Southern Italy and Greece.  It is characterized by hot, nearly rainless summers, and mild rainy winters.  It is a pleasant climate and is conductive to the bountiful agriculture produce produced in this region.  Much of the world’s most renowned wines are produced in this region and in other regions of the world [wwclimc] (i.e., California) where this climate occurs.
