Environmental pollution and meteorological

Environmental pollution and meteorological

Know the environment Environment as a set of natural systems in which they live rights. These systems enjoy in between a so-called balance the ecological balance and this is the balance that preserves each part in the system the possibility of its existence and prosperity. In the event of a breach of this balance, the ecosystem in all its molecules act to re-balance.
Example: a fire partially in the woods will work to increase the carbon dioxide and then increase in the vegetative growth of the plants surviving because of the abundance of carbon dioxide by photosynthesis of plants and then make up the shortfall in the forest resulting from fire and therefore the return rates of oxygen and carbon dioxide to normal .But if the fire was comprehensive, the process of recovery from the disorder will become impossible or too long and thus will start the rest of the ecosystem to be affected and thus increasing environmental unbalance condition later, leading to what is known as environmental pollution and ecological disaster.
Environmental pollution
Defined as an imbalance in the system of ecological balance by changing recipe (chemical, physical, biological) or more of the attributes of partial or more of the constituent particles of the system due to environmental behaviors exercised rights.
Types of environmental pollution
1 - Physical pollution: One of the most important forms of noise pollution, light, radiation and solid waste pollution
2 - chemical pollution: One of the most important forms of chemical pesticide contamination, chemical detergents, fertilizers, oil spill, toxic gases.3 - biological contamination: One of the most important forms of microbial contamination and overlapping environmental regulations.
Sources of pollution- The use of pesticides and chemical fertilizers in agriculture- The use of chemical detergents- Wastewater discharge to the sea, rivers and dams- Oil Spill- Thermal pollution: the warming of water because of its use in the cooling power plants- Industrial waste such as asbestos and heavy-aided- Remnants of nuclear reactors, a radioactive material impact lasts for a very long time- Solid waste left over from behind human activities- Gases resulting from human activities and industrial transportation- Human populations and the resulting pollution noisy and optical and chemical- Fires and wars- Transport of living animals and plants from their native habitats to other environments- The destruction of forests and natural environments
Exposed all the components of the earth's pollution is the most important targets water and air pollution and because of the general session of the air and water, all of the water, air and soil exchange constantly pollutants and published in all the planet.
Some of the most important aspects of pollution
The increased concentration of certain gases in the atmosphere from natural focus (one of the most important of these gases carbon dioxide) works to prevent from terrestrial radiation leakage into outer space where that works on solar radiation heating the earth, which in turn is based on this heat radiation toward space. Featuring carbon dioxide permeability of solar radiation, but not force the radiation Ground, which works to heating the earth's atmosphere by booking part of the terrestrial radiation, but in the event of increased concentration of carbon dioxide, the share of retained within the atmosphere will increase, which works to increase the Earth's temperature and thus a change in the global climate and an increase in sea levels at the expense of the polar ice and there are a lot of phenomena that confirm such a scenario.
2 - Ozone depletion: ozone depletion
Produces some Refrigeration Industries and gas payment and firefighting and waste aviation jet exhaust some vehicles called CFCs (CFC) or الفريونات which reacts with ozone gas (O3) in the stratosphere converted him into oxygen (O2).'s Mission is stratospheric ozone in UV absorption preventing them from reaching the Earth's surface and this caused the high temperatures in the stratosphere. arrival of ultraviolet radiation (UV) to the earth's surface will lead to increased heat also in addition to the threat to human health.
CCL3F CL + CCL2F
CL + O3 CLO + O
CLO + O CL + O2
There are a lot of studies confirm the erosion of the ozone layer, especially over the South Pole and the continued erosion of this layer at the same level, the risk of UV radiation on forest and marine life will escalate, especially coral reefs, which are a major source of oxygen seas.
Observed in recent years that there are years recorded the temperature of sea water and the oceans numbers higher than normal levels and believes that for many phenomena previous role in this was also noted that there is a clear link between the rise and some weather phenomena destructive such as hurricanes, floods and drought.Of the most famous of these Views El Nino (Nino), a warming of the ocean surface off Chile are higher than normal and is reversible phenomenon La Nina (Nina) and has been associated with El Nino cyclones in the Atlantic region and the occurrence of drought in the interior regions of South America. In the Eastern Mediterranean region there is no proof that affected the region El Niño but Rain region linked to the phenomenon of Nao (NAO) which is associated with warm waters of the Atlantic as well.
Temperature waters of the seas and oceans
4 - acid rain (acid rain)Produced from the burning of fossil fuels many of toxic gases such as carbon and nitrogen oxides and sulfur, which in turn melt into raindrops, causing the so-called acid rain. It is known that acid rain is working on deforestation and the fall of such a rain at sea helps to reduce the pH (PH) of water, which negatively affects marine organisms, particularly coral. In Jordan might work like this rain to accelerate the rate of corrosion effects, which is the source main income.

Meteorological role
 
Associated with environmental science and pollution meteorology, like other sciences, such as agriculture, water and so the overlap is clear and noticeable between air systems and wandering pollutants Mmttih wind and water cycle. The acquisition of meteorological services in the world for a large number of monitoring stations weather makes them means effective control of elements of the environment as a international organization to care for and organize the work of meteorological services in the world helped to establish many programs environmental control in the world is the most important program Ozone (SAF-O3 ) orbit by the Finnish Meteorological Department and chemistry of the atmosphere control programs of the World Meteorological Organization (WMO)(WMO), which operate under the name of global atmospheric watch. The presence of numerical models to predict the weather in both its short-and long-term (global and regional) with capacities of dissolution powerful in many meteorological services in the world shares in the activation of research programs in the field simulate reality and predict the future and I've had the results of these programs the greatest impact to sound the alarm for many environmental issues and which later became a top priority for states and international organizations.
How the temper of pollution

1 - to reduce dependence on fossil fuels and start heading to rely on renewable energy sources such as solar, wind and biomass.

2 - reducing dependence on chemicals such as pesticides, fertilizers, detergents, and start relying on natural fertilizers and biological control methods and biodegradable detergents.
3 - changing consumer habits and the playboy lifestyle of many people through increased environmental awareness and the development of the spirit of citizenship and belonging.
4 - to stop the depletion of natural resources such as forests and fisheries and other orientation toward moderation.
5 - purifying wastewater before being discharged to the sea.
6 - to stop the production of harmful ozone gases and search for alternatives though it is available
7 - Work on the legislation and laws able to deter offenders and abusers of the environment and work to stimulate international cooperation in this area through the development of a global agreements and the exchange of experiences and qualifying.
