Thus, one brief relation of these atmospheric systems and its characteristics becomes, emphasizing its places of origin and performance, beyond explanar the dynamism that they cause. This study one gave through a reading on the atmospheric systems and the climatic controls, that are the responsible ones for the movement of air. Air masses, fronts, movement of air. The atmospheric systems? the air masses the fronts related they, are the meteorological phenomena that more influence the time in our continent. The comment of these phenomena is of utmost importance for a detailed knowledge of the climate, being thus the analysis of the atmosphere through the equipment job new, increased the study of the different fields of pressure, which are formadores of the controls climatic. These studies of the atmospheric dynamics have as objective to describe and to predict the meteorological conditions, identifying the climatic controls, which cause the climate of one definitive region. From this form, the air masses dislocate in the direction Equator-Polar region, generating atmospheric discontinuities that are the fronts, them determine the climates of the subtropical and tempered regions.

The movement of air is supported by the different distribution of the energy solar and influenced by the rotation of the Land. These movements are the determinative ones of the climatic zones in the different places of the Planet. Thus, the average position of the main centers of action and the dominant winds cause the dynamism of air on the surface. Being thus, it can be inferred that the climatic types of Brazil are given through the great movement of the air, caused for the dynamism of the atmosphere. With this, one perceives that the Brazilian territory sufficiently is influenced by air masses and front.

The latitude also influences directly in the amount of radiation that arrives the terrestrial surface, therefore the terrestrial axle possesss average inclination of 23, such characteristic in accordance with the period of the year, makes with that a hemisphere is more ' ' iluminado' ' , that is, it receives greater radiation that the other, thus, the stations of the year, as much the main ones as summer and winter, as the transitory ones as autumn and spring, is alternated in each hemisphere, therefore, the Land possesss rocking of different radiation during the sazonais periods of the stations of the year. The altitude of the Sun, understood here as the angular relation between the incident ray and the tangent formed in one determined point of the terrestrial surface, also it affects in the amount of incident solar radiation on the Land, therefore how much lesser the surface will be the angle of the tangent formed in relation, minor will be the bigger absorption and Albedo, that is, capacity of reflection of energy proceeding from the solar ray for the surface, in the same way how much bigger it will be the formed angle, more intense it will be the absorption of the incident ray and lesser it will be its reflection. Soon, during the first hours of the morning and in entardecer the Sun forms the lesser angles in relation the terrestrial surface what it causes to minor absorption of energy and greater reflection process, with the evolution of the day the Sun arrives at its maximum point of altitude to the noon forming great and straight angles in the tangent with the surface, in this case the energy absorption will be bigger while the reflection will be neglected. Inside of as the group of factors that influence the distribution of insolation on the terrestrial surface, has it distribution of the liquid and terrestrial surfaces, beyond the rise and the behavior of the same ones.

Therefore it can be affirmed that it has extreme dependence of the people in relation to ' ' gold negro' '. 3,3 Society subordinated to the oil and the energy In the present time would be difficult to imagine as it would be an exempt reality of the energy consumption. This brings in sight a relation of dependence between the people and coveted ' ' gold negro' '. Our society depends on the oil. Since that this started to be used, in the ends of century XIX, as combustible, it each more important time took a paper.

Nowadays he is used to produce electricity, as combustible for the majority of the ways of transport and many domestic uses, to produce plastic, without which our society would be very different of we know as it. Any doubt does not exist of that the energy is of an extreme importance for our civilization. Of fact, can be said that all the economy is dependent of it, as already it was mentioned. Thus, it is natural that certain reactions of panic occur when is mentioned that the oil reserves are close to its end. The current reserves are enough to more than keep the current production during 40 years and the spare level of the reserves is sufficiently satisfactory.

The demand of the developed countries practically is contained to the current levels and it does not grow more in a direct relation with the growth of the GIP. However the energy dependence is the consequence of this picture, that its elements more than if complete to form them pillars of the globalization. 4 the FUTURE WITHOUT OIL What to make when the oil to deplete? She is one of the questions that guide the reason of the suitable people to its massivo consumption. The oil is a valuable resource, without which the modern life, as we know, would not be possible.


Solar Radiation

The dynamics of the solar radiation and the main aspects of the energy rocking global Anderson Azevedo Mesquita* the Sun is great astro of the universe, is of it that energy waves are radiated that if propagate for all space and that they reach and they give to dynamics the main physical, biological and chemical functions of the systems and subsystems that receive the radiation solar as form from motor energy. The Sun supplies 99.97% of the energy that is used by the systems that form the Land, presents capacity of production of huge energy, the radiated ratio is of about 56 x 10 v calories of energy per minute, where the Land intercepts only 2,55 x 10 x calories, sum enough to supply the necessity and the energy consumption of the world 30 a thousand times during 01 (hum) year. (AYOADE, 1986) the energy radiated for the Sun is propagated in the space for intermediary of electromagnetic waves that present specific behavior and lengths. Second, Tubelis (1980) to the spectral distribution of solar radiation is indicated in the band of wave length between 0,3 and 4 microns, therefore, the solar radiation is called of radiation of short wave, being the main waves radiated pertaining to this group, of the ultraviolet band, the visible band and the infra red ones, being the radiated respective proportionality in the Land of 9%, 41% and 50%. When arriving the Land, the solar radiation will interact the principle with atmosphere and all its composites, the radiation will go to cross the atmospheric layers and sublayers and will suffer processes from attenuation. Such processes of attenuation, according to Tubelis (1980), are three: 1.

Scattering for particles of the atmosphere or diffusion; 2. Selective absorption; 3. Process of absorption and reflection for clouds. The particle scattering or diffusion is the scattering of the solar ray caused by diverse gaseous composites or of solid or liquid microparticles that are in suspension in the atmosphere, depending on characteristics of these elements, and the type of wave emitted for the Sun that is attenuated by the process of scattering or diffusion, abundance of certain colors of light in the visible portion of the solar specter can be had greater, for example, the blue light more is spread of what the red color, therefore the dominant aspect of the blue color in the sky.

We know that the man participates of the nature since its sprouting in the Land and he always needed the food, the water and the shelter that is of basic importance for its survival. Second, Milton Saints. This generalized natural way was used for the man without great transformations. The techniques and the work if married the gifts of the nature, with which if they related without another mediation.

(SAINTS, 2009.p. 235) Thus, in all the historical stages of the humanity made use of the nature, first for its proper sustenance and later to produce excesses, especially after the Industrial Revolution. In fact, the natural resources that if find in the planet are of vital value for its half of consumption economic and ambient partner as: the ground, the water, the oxygen, deriving energy of the Sun, the forests, the animals, amongst others. also understanding, that the natural resources can be recomposto after extracted by the antrpicas activities, through the replacement that occur from time to time with the great diversities of natural resources you renewed as: the aeolian energy (winds), the solar energy (solar radiation), waves of the sea, hidroeletricidade, biomass and geothermal energy. Allowing in this way, the replacement of the resources used to advantage in the place, enabling to be made by the man or of course, the proper environment. On the other hand, we know that the natural resources not-you renewed are those that after finish intense exploration carried through for the activities it man, demanding much time to be rehabilitated. understanding that all natural resources must and can be governed in a sustainable way in the objective to guarantee its replacement and regeneration in the environment, exactly in circumstances of intense exploration of these resources, always will have risks to occur a decurrent impoverishment of an ecological disequilibrium.
