1972 Iran Blizzard
The Iran blizzard of February 1972 was the deadliest blizzard in history. A week-long period of low temperatures and severe winter storms, lasting 3–9 February 1972, resulted in the deaths of over 4,000 people. Storms dumped more than of snow across rural areas in northwestern, central and southern Iran. Southern Iran received as much as of snow, burying at least 4,000 individuals. According to contemporary reports by the newspaper ''Ettela'at'', the city of Ardakan and outlying villages were hardest hit, with no survivors in Kakkan or Kumar. In the northwest, near the border with Turkey, the village of Sheklab and its 100 inhabitants were buried. Meteorological progression A series of snowstorms at the end of January had already accumulated over western Iran. Passing from Azerbaijan to Iran between February 3 and 8, the blizzard left of snow, which is equivalent to a 2 and-a-half story building. The wind and snow resulted in the breakage of trees and power lines. The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Extratropical Cyclone
Extratropical cyclones, sometimes called mid-latitude cyclones or wave cyclones, are low-pressure areas which, along with the anticyclones of high-pressure areas, drive the weather over much of the Earth. Extratropical cyclones are capable of producing anything from cloudiness and mild showers to severe gales, thunderstorms, blizzards, and tornadoes. These types of cyclones are defined as large scale (synoptic) low pressure weather systems that occur in the middle latitudes of the Earth. In contrast with tropical cyclones, extratropical cyclones produce rapid changes in temperature and dew point along broad lines, called weather fronts, about the center of the cyclone. Terminology The term " cyclone" applies to numerous types of low pressure areas, one of which is the extratropical cyclone. The descriptor ''extratropical'' signifies that this type of cyclone generally occurs outside the tropics and in the middle latitudes of Earth between 30° and 60° latitude. T ...

Pahlavi Iran
The Imperial State of Iran ( fa, کشور شاهنشاهی ایران, ), also known as the Imperial State of Persia, was the official name of the Iranian state under the rule of the Pahlavi dynasty. It was formed in 1925 and lasted until 1979, when the Pahlavis were overthrown as a result of the Iranian Revolution, Islamic Revolution, which abolished Iran's continuous monarchy and established the present-day Iran, Islamic Republic of Iran. The Pahlavi dynasty was founded in 1925 by Reza Shah, a former brigadier-general of the Persian Cossack Brigade. His reign lasted until 1941, when he was forced to abdicate by the Allies of World War II following the Anglo-Soviet invasion of Iran. He was succeeded by his son, Mohammad Reza Pahlavi, who was the last List of monarchs of Persia, Shah of Iran. The Pahlavis came to power after Ahmad Shah Qajar, the last Iranian ruler under the Qajar dynasty, proved unable to stop encroachments on Iranian sovereignty by the United Kingdom and the ...

Weather Events In Asia
Weather is the state of the atmosphere, describing for example the degree to which it is hot or cold, wet or dry, calm or stormy, clear or cloud cover, cloudy. On Earth, most weather phenomena occur in the lowest layer of the planet's atmosphere of Earth, atmosphere, the troposphere, just below the stratosphere. Weather refers to day-to-day temperature, precipitation, and other atmospheric conditions, whereas climate is the term for the averaging of atmospheric conditions over longer periods of time. When used without qualification, "weather" is generally understood to mean the weather of Earth. Weather is driven by atmospheric pressure, air pressure, temperature, and moisture differences between one place and another. These differences can occur due to the effect of Sun angle on climate, Sun's angle at any particular spot, which varies with latitude. The strong temperature contrast between polar and tropical air gives rise to the largest scale atmospheric circulations: the ...
