In general, meteorology is the study of the atmosphere, especially in terms of forecasts and weather phenomena. WMO (World Meteorological Organization) who take shelter under the United Nations, together with 188 members, all the time always pay attention to the phenomena that occur on earth.
Each year, WMO always launched an international movement to make observations, research and prevention efforts to address the decline in the degree of damage to the world’s climate, global warming and so forth. For example, through discussions, seminars or other scientific activities, followed by experts from the many ways of disciplines, ranging from experts meteorology, climatology, environment and others.
Weather is defined as the average state of the air at a certain time limit and place. While the climate comes from the Greek, Klima, defined as a tendency (inclination). Climate represents average weather conditions in a wide area within a period of time. WMO climate defined as the total of all atmospheric elements such as solar radiation (long and intensity), humidity, clouds, rain and wind (direction and velocity) within a period of 30 years.
So explain the earth’s climate system in the future, let alone memprediksikannya is not an easy job. There are many factors and variables that influence it. These factors are generally categorized into three groups. terebut third factor is:
1. Covering all elements of the carrier directly and indirectly the climate system itself, such as the dynamics of glaciers, oceans and natural patterns of the surface of the earth’s climate (the water cycle, atmospheric circulation, ice and snow, water vapor and clouds).
2. The forces that affect other major factors such as global warming due to greenhouse gas emissions, a shift in plate tectonics, and solar radiation, including volcanic activity and changes in Earth’s orbit.
3. Human activities such as the use and burning of fossil fuels (petroleum), aerosols (CFC gases that are released air conditioning and refrigeration), industrial, forest logging and land use changes.
Peak Fragility
As we know, climate elements such as temperature and rainfall, highly dependent on the energy balance between the earth and atmosphere. On average amount of solar radiation is absorbed by the earth would be equal to the amount of radiation released into the atmosphere, so that radiation is released causing our earth’s atmosphere to warm. Solar radiation and the atmosphere is the main determinant of the earth’s climate system.
Of all the global climate change can be seen that there is no indication of the disaster will subside. Even recent developments seem more frequent and widespread in areas previously not a disaster.
This can be studied and examined as the impact of weather and climate variability. Current conditions are so alarming, some time ago appears catastrophe that took the lives property and life, ranging from floods, flash floods, landslides, high winds, thunder and lightning flashes that often take casualties.
These events in fact have become the focus of attention of researchers and practitioners concerned. But not yet seen efforts in disaster management, especially formulate a comprehensive planned course of action in mitigation and anticipation. This perception is presented as experience shows, after the disaster passes, the natural condition again abandoned and forgotten without any efforts to prevent similar disasters in order not happen again.
Natural conditions and environment is currently in the top of fragility to withstand extreme weather conditions exist especially extreme weather. Some time ago we disusguhi extreme hot weather, direct heat we feel when out of the house. The weather grew hot because there is no longer sufficient to hedge trees to reduce heat.
In some big cities, the rain has caused flooding a little while because of water channels and rivers are filled with garbage. Flash floods and landslides often occur at this time due to the loss of vegetation on the slopes or up the river, but not too heavy rainfall flushed the area. This indicates that the actual weather conditions ‘not cruel’ but humans destroy nature and the environment resulting in disaster.
Warning
Information and warnings to alert the public to deal with the effects of weather disasters in order not to be very important. Weather (rain, heat, high winds and so on) is something that can be expected but can not be prevented his arrival. So the important thing is the anticipation of the weather conditions are expected to appear for no adverse impact to human disasters.
This warning intentionally is raised to remind us all that the natural conditions and environment around us is increasingly vulnerable to disasters due to weather and climate that tend esktrim. Global natural phenomenon of El Nino and La Nina, gave instructions that the weather and climate patterns in the universe of situations and conditions are not uniform with the level of the emergence of trends in weather and climate conditions esktrim esktrim wet or dry.
Esktrim dry periods tend to be longer, and esktrim wet tend to be short but high intensity rainfall which is sometimes followed by the emergence of strong winds and lightning bersahut-replication. Need an education to the community as a whole that they should remain vigilant because they live in disaster prone areas.
