PLANET OF THE CLIMATE

     The climate of the Earth n'is the same over entire surface of the Globe. It changes from one continent to another, in other countries, one province to another, sometimes from one city to another.It follows from the distribution of atmospheric conditions in a given area during a limitedperiod of time.

       These climate cycles caused by the interaction between the atmosphere, hydrosphere, lithosphere and biosphere, which under the effets of solar radiation, the direction and temperature of ocean currents, regulate the climate of the Planet. The relief of the Continents forms a physical barrier to these exchanges and modifies the distribution of heat and precipitation. Hense the different climates on the surface of the Earth during the season. Planet is experiencing a variety of climates, ranging from polar climate at high latitudes to tropical clmate along the equator.

        In theory or could classify conditions of the Earth into three categories: an area where the climate is always warm on one side and the other from the equator to beyond the tropics, and two cold regions in the polar cilcles. But in reality the Globe is exposed to a wider variety of climates, which depend on fluctuations in ocean currents, volcanic eruptions, solar radiation, astronomical phenomena and other factors ignored which'involved in clmate system Earth.

        WET TROPICA CLIMATE: the climate on both sides of the Equator, between 15 and 25 degres latitude north and south. The average temperature is 16° C and the year is divided into a dry season (summer) and a wet (winter).

      TROPICAL DRY CLIMATE: it is characterized by a climate of greater evaporation precipitation. The average temperature is around 18° C and the vegetation is virtually nonexistent. The climate ranges from 10 to 35 ° letitude north and south. It is found in the desert or semi-desert, normal surrouded by motains to the west and centerof the Continents.

         SUBTROPICAL CLIMATE: climate is normal at latitudes 25-40° north and south of the Mediterranean Western. And characterized by a real cold season under the effects of the movement of polar air masses. Exemple: cold waves with temperatures of -20 and -30° C, observed in Western Europe and North America in December 2011 and February 2012. The subtropical climate is subject to abrupt phenomena such as thundestorms, tropical storms, floods and cyclones. Two types of climate can be classified as subtropcal: climate on the Western façades and the climate of the eastern Mediterranean façades. Both climates have in common mild winters sometimes, but tropcal air masses  bring them hot sumers that canexcced 40° C. As in scorching temperatures in 2003 and 2004 in the souh Europe.

            TEMPERATE CLIMATE; this is the climate that divides the year into two seasons, on hot and on cold. It is subject    to the effects of océan climate on the on hand, and the continental climate on the other. Temperatures are generally moderate. 

        CLIMATE SUBARTIC: can not find this kind of climate in the nortern hemisphere. The climate is intermediate between the temperate  and polar climate. Summers are hot winters less rigorous than in the temperate climate.

             POLAR CLIMATE: the climate Poles, cold all year round, with temperatures down to -90° C.  

            TIPPING BIPOLAR TEMPERATURES: polar climate switches from on cluster to another. When a pole warms and cools the other the reverse. These phases heat-up/cool-down following successive cycles of a few decades. And the link between the north pole and the south pole is the Atlantique ocean. This allows some scientists to advance the idea that the current warming Arctic Continent, may depend, a least in part, from changes in Atlantic circulaion, temperature and direction of ocean currents.

          

           When addressing the problem of rising temperatures of the Planet, we are facd with the difficult question of which ot these various climates and heast up than others. And why.

            We do not have the answer. We only know that during a period of rising temperatures, as is the case of the Earth right now, the Artic circle and real warms up faster than the rest of the Earth's suface (the last century when the temperature  average Planet has increased only 0,8° C, the Arctic polar region rose from 2° C).

           We also know with absolute certainty that the current volume of CO² released into the atmosphere by humans, has no impact on climate change any of latitudes in summer or winter. And against all the phenomena that rule the climate of the Earth, Man is a newborn evolves on the surface of the Planet that turns slowly and advanced by. It can only adapt and deal with it, leaving the nature of the task clear thermodinamic imbalances that are the cause of climat variations such and such place of the Globe. She did comme out better than without the intervention often ubecoming humans.

                                                                                                                                                José Lino

Very nice

 l loved this blog because of its title which is very impressive and unique from others. I have never read this term " planet of climate" but I am student of geography on bestdissertation.com that’s why this article attracted me soo much. I hope everyone will find it interesting and useful as well.
