Frequently Asked Questions
Climatology: Climatology is a scientific study of climate, that is, the description and presentation of the elements, the analysis of factors, the difference between the climes and the application of climatic information in solving the problems of society, in other words, the goal of climatology is to discover and explain natural behavior The atmosphere and exploitation of it for the benefit of man. Climatology has been known to humans since far away, and people considered it to be the long-term state of the atmosphere, and it was described by expressing rainy days, dry air, full of dust, northern or southern winds, and so on.
Meteorology: On a global scale, a mixture of atmospheric physical studies and their phenomena is divided into two main parts: dynamic meteorology: studied by the laws of mechanics and thermodynamics of atmospheric states. Synoptic Meteorology: Experimental and synoptic maps prepared at certain times. The weather conditions are being studied and one of its major tasks is the prediction of future air
What is elenium
El Niño / South Oscillation is one of the most important and most significant events that has led to the emergence of large weather abnormalities in many parts of the world. World meteorologists and oceanographers have done a lot of research in recent years about the mechanism for the creation of El Niño and the interactions between the oceans and oceans, in particular extensive studies of the uneven sea temperature and atmospheric pressure fluctuations in the years when El Niño Rakh It says that the set of these changes is called the South Oscillation, which is called the ENSO (ElNino Southern Oscillation), a combination of the two words of El Nino and the South Oscillations. For the first time, Wacker (1932) and Pelice (1937) referred to the oscillation in surface pressure on a global scale and called it the South Oscillation of SO. So, SO is a global telecommunication model in the atmosphere, and is called the other South Telecommunications Patterns, especially the North Atlantic and Pacific Northwest, due to its clearness. SO centers are related to each other through an orbit around the east to west along the equator plate with the ascents of the air in the west of the Pacific and the descent of the air in the eastern Pacific Ocean, thereby shaping the movement created by the Bayges (1969) Called. El Nino is an oceanic component of the ENSO, and it appears with a great transformation at sea temperature levels in a tranquil region.
Air Frontier: The line between the hot and cold air mass says that the dominant position (ie, a state where the cold air mass is dominated by heat or vice versa) is called the frontier.
Air Masses: An air mass is a huge amount of air, with its physical characteristics, particularly in terms of temperature and humidity, and the rate of lapse rate in the horizontal plane for nearly hundreds of kilometers, is almost identical.
Warm fronts: A warm front is the edge during which hot air is replaced by air. If the direction of movement of the masses of the air is such that the warm air gradually passes through the surface of the ground, where there has been cold air before, the front will form a warm front. On the meteorological maps, the heated front is usually drawn in half of the black circles and on the side where the front moves to the other side. On printed maps, the hot front is marked with a full red and red line. The result of the formation of a warm face is to create a fairly thick covering of the cloud on the surface of the front and near its trail and the rain is uniform.
Cold Fronts: On cool fronts, cold weather replaces the air. The black blades on the line representing the front mark the front of the cold and are always placed on the direction in which the front moves in that direction. Meteorological maps of the Cold Fronts are marked with a bold blue line. The result of the formation of a cold front is the formation of clouds of cumulus and cumulonimbus, accompanied by rainstorms.
Swing: The area of ​​high pressure is a non-regular circle, in which direction is opposite to the direction of movement that is available in low pressure centers.
What is the temperature
Temperature is one of the basic elements of air recognition. Due to irregular solar energy absorption by the earth, the temperature of the air on the surface of the earth is very variable, which, in turn, causes other changes in other elements of the air. The temperature is measured by the thermometer.
What are the types of thermometers?
1 - Normal Thermometer (Standard Thermometer)
2 - Max Thermometer
3 - Minimum Thermometer
4 - Minimum Max Thermometer
5 - Thermograph
What is greenhouse effect?
It's called a greenhouse gas, a collection of gases that keep some of the sun's energy in the atmosphere and cause the atmosphere to warm up. Water vapor (H2O), dioxide nitrogen (NO2), carbon dioxide (CO2), and methane (CH4) are the main greenhouse gases. If these gases were not in the atmosphere, the solar energy would return to space again, and the ground would be 33 degrees Celsius cooler than today. The greenhouse effect is said to increase the Earth's temperature due to the presence of greenhouse gases in the Earth's atmosphere.
What is lightning
Lightning or lightning is an intense, very fast evaporation in the air, and is the same electrical drain that produces light and sound. Before the lightning storm begins, the clouds become overwhelmed by processes that are usually positive, this time, it induces a negative earth surface, and In this way, the cloud-air and earth complex becomes a very large capacitor, which momentarily rises to the instant, so the potential difference between the two poles is increasing. The amount of this electric charge is so high
