Sabzevar (; ) is a city in northeastern Iran. It is located in the Central District of Sabzevar County, Razavi Khorasan province, serving as the capital of both the county and the district. History The history of Sabzevar goes back to the 1st millennium BC. Ancient remains include fire-temple Azarbarzin which is still visible. After the Mongol invasion of Iran, the city was the first part of Iran that moved towards its freedom, under the lead of the Sarbedaran movement. In 14th century Timur invaded Iran and destroyed the city completely. Contemporary sources mention 90,000 people having been murdered by Timur. After killing all men in the town, he cut their heads and made 3 pyramids of the heads, in what is now the modern Sarberiz (meaning "Place of heads") square. Sabzevar Province had been lost by the Safavids to the Uzbeks of Transoxiana, but was regained following a Safavid counter-offensive around 1600, along with Herat and Farah. The city suffered a flash fl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Thunder
Thunder is the sound caused by lightning. Depending upon the distance from and nature of the lightning, it can range from a long, low rumble to a sudden, loud crack. The sudden increase in temperature and hence pressure caused by the lightning produces rapid Thermal expansion, expansion of the air in the path of a Lightning strike, lightning bolt. In turn, this expansion of air creates a Shock wave, sonic shock wave, often referred to as a "thunderclap" or "peal of thunder". The scientific study of thunder is known as ''brontology'' and the irrational fear (phobia) of thunder is called ''brontophobia''. Etymology The ''d'' in Modern English ''thunder'' (from earlier Old English ''þunor'') is epenthetic, and is now found as well in Modern Dutch ''donder'' (cf. Middle Dutch ''donre''; also Old Norse ''þorr'', Old Frisian ''þuner'', Old High German ''donar'', all ultimately descended from Proto-Germanic *''þunraz''). In Latin the term was ''tonare'' "to thunder". The name of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
NOAA
The National Oceanic and Atmospheric Administration (NOAA ) is an American scientific and regulatory agency charged with forecasting weather, monitoring oceanic and atmospheric conditions, charting the seas, conducting deep-sea exploration, and managing fishing and protection of marine mammals and endangered species in the US exclusive economic zone. The agency is part of the United States Department of Commerce and is headquartered in Silver Spring, Maryland.

The National Centers for Environmental Information (NCEI) is a U.S. government agency that manages one of the world's largest archives of atmospheric, coastal, geophysical, and oceanic data. The current director is Deke Arndt. NCEI is operated by the National Environmental Satellite, Data, and Information Service (NESDIS), an office of the National Oceanic and Atmospheric Administration (NOAA), which operates under the U.S. Department of Commerce. In addition to archiving data, NCEI develops products and services that make data readily available to scientists, government officials, the business community, academia, non-governmental organizations, and the general public. NCEI provides environmental data, products, and services covering the depths of the ocean to the surface of the Sun. History Formation NCEI was created in 2015 from the merger of three NOAA data centers: * National Climatic Data Center (NCDC) * National Geophysical Data Center (NGDC) * National Ocean ...

Köppen Climate Classification
The Köppen climate classification divides Earth climates into five main climate groups, with each group being divided based on patterns of seasonal precipitation and temperature. The five main groups are ''A'' (tropical), ''B'' (arid), ''C'' (temperate), ''D'' (continental), and ''E'' (polar). Each group and subgroup is represented by a letter. All climates are assigned a main group (the first letter). All climates except for those in the ''E'' group are assigned a seasonal precipitation subgroup (the second letter). For example, ''Af'' indicates a tropical rainforest climate. The system assigns a temperature subgroup for all groups other than those in the ''A'' group, indicated by the third letter for climates in ''B'', ''C'', ''D'', and the second letter for climates in ''E''. Other examples include: ''Cfb'' indicating an oceanic climate with warm summers as indicated by the ending ''b.'', while ''Dwb'' indicates a semi-Monsoon continental climate, monsoonal continental climate ...

Cold Semi-arid Climate
Cold is the presence of low temperature, especially in the atmosphere. In common usage, cold is often a subjective perception. A lower bound to temperature is absolute zero, defined as 0.00K on the Kelvin scale, an absolute thermodynamic temperature scale. This corresponds to on the Celsius scale, on the Fahrenheit scale, and on the Rankine scale. Since temperature relates to the thermal energy held by an object or a sample of matter, which is the kinetic energy of the random motion of the particle constituents of matter, an object will have less thermal energy when it is colder and more when it is hotter. If it were possible to cool a system to absolute zero, all motion of the particles in a sample of matter would cease and they would be at complete rest in the classical sense. The object could be described as having zero thermal energy. Microscopically in the description of quantum mechanics, however, matter still has zero-point energy even at absolute zero, beca ...
