2021 Henan Floods
China's Henan Province experienced flooding between 17 and 31 July 2021 as a result of heavy rainfall. On July 20, Zhengzhou, the provincial capital, recorded of rainfall within an hour, the highest ever figure recorded since measurements began in 1951. On 2 August 2021, provincial authorities reported 302 deaths (292 in Zhengzhou), and over 50 missing people. Later, government investigations led to conclude that provincial officials had “deliberately impeded and withheld reports of up to 139 cases”, and that the full death toll was 398. The floods caused the evacuation of 815,000 people, and affected 14.5 million people around the province. The intensity of the floods was believed to have been amplified by extreme weather caused by climate change. Meteorological synopsis Several factors were attributed to the unusual and severe floods in Henan. The subtropical high (system of high atmospheric pressure) in the western Pacific as well as the continental high-pressure area i ...

Mesoscale Convective Vortex
A mesovortex is a small-scale rotational feature found in a Thunderstorm, convective storm, such as a quasi-linear convective system (QLCS, i.e. squall line), a supercell, or the eyewall of a tropical cyclone. Mesovortices range in diameter from tens of miles to a mile or less and can be immensely intense. Eyewall mesovortex An ''eyewall mesovortex'' is a small-scale rotational feature found in an eyewall of an intense tropical cyclone. Eyewall mesovortices are similar, in principle, to small "suction vortices" often observed in multiple-vortex tornadoes. In these vortices, wind speed can be up to 10% higher than in the rest of the eyewall. Eyewall mesovortices are most common during periods of intensification in tropical cyclones. Eyewall mesovortices often exhibit unusual behavior in tropical cyclones. They usually revolve around the low pressure center, but sometimes they remain stationary. Eyewall mesovortices have even been documented to cross the eye of a storm. These pheno ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Zhengzhou Subway Flooding
The Zhengzhou subway flooding incident refers to the severe flooding that occurred on Zhengzhou Metro Line 5 on July 20, 2021, during a heavy rainstorm. Despite the weather, the metro line continued to operate, and rainwater broke through the retaining wall of the Wulongkou parking lot, flooding the train tunnel. Official reports from the government stated that the incident resulted in 14 deaths and 5 injuries. However, the death toll has been widely questioned because the trains were covered with black cloth during the subsequent search and rescue operations, preventing the inspection of their interiors. Background Since July 17, 2021, continuous heavy rainfall has caused flooding in various locations in Henan Province, People's Republic of China, including Zhengzhou, Luohe, Kaifeng, Xinxiang, Hebi, and Anyang. Zhengzhou experienced a record-breaking maximum hourly rainfall of 201.9 mm, the highest since meteorological records began. Nineteen weather stations, including ...

Train From Xingtai To Zhengzhou After The Flood 2021-07-21
A train (from Old French , from Latin">-4; we might wonder whether there's a point at which it's appropriate to talk of the beginnings of French, that is, when it wa ... , from Latin , "to pull, to draw") is a series of connected vehicles that run along a railway track and Passenger train, transport people or Rail freight transport, freight. Trains are typically pulled or pushed by locomotives (often known simply as "engines"), though some are self-propelled, such as multiple units or railcars. Passengers and cargo are carried in railroad cars, also known as wagons or carriages. Trains are designed to a certain gauge, or distance between rails. Most trains operate on steel tracks with steel wheels, the low friction of which makes them more efficient than other forms of transport. Many countries use rail transport. Trains have their roots in wagonways, which used railway tracks and were powered by horses or pulled by cables. Following the invention of the steam locomotive i ...

Waterlogging (agriculture)
Waterlogging water is the saturation of soil with water. Soil may be regarded as waterlogged when it is nearly saturated with water much of the time such that its air phase is restricted and Hypoxia (environmental), anaerobic conditions prevail. In extreme cases of prolonged waterlogging, anaerobiosis occurs, the roots of mesophytes suffer, and the subsurface reducing atmosphere leads to such processes as denitrification, methanogenesis, and the reduction of iron and manganese oxides. All plants, including crop, require Earth's atmosphere, air (specifically, oxygen) to respire, produce energy, and keep their cells alive. In agriculture, waterlogging typically blocks air from getting to the roots. With the exception of rice (''Oryza sativa''), most crops like maize and potato, are therefore highly intolerant to waterlogging. Plant Cell (biology), cells use a variety of signals such the oxygen concentration, plant hormones like ethylene, energy and sugar status to acclimate to ...

Aqua (satellite)
Aqua (EOS PM-1) is a NASA scientific research satellite in orbit around the Earth, studying the Precipitation (meteorology), precipitation, evaporation, and Water cycle, cycling of water. It is the second major component of the Earth Observing System (EOS) preceded by Terra (satellite), Terra (launched 1999) and followed by Aura (satellite), Aura (launched 2004). The name "Aqua" comes from the Latin word for water. The satellite was launched from Vandenberg Air Force Base on May 4, 2002, aboard a Delta II Launch vehicle, rocket. Aqua operated in a Sun-synchronous orbit as the third in the satellite formation called the "A-train (satellite constellation), A Train" with several other satellites (OCO-2, the Japanese GCOM, GCOM W1, PARASOL, CALIPSO, CloudSat, and Aura (satellite), Aura) for most of its first 20 years; but in January 2022 Aqua left the A-Train (as Cloud Sat, CALIPSO and PARASOL had already done) when, due to its fuel limitations, it transitioned to a free-drift mode, w ...

Relief Rain
In meteorology, the different types of precipitation often include the character, formation, or Phase (matter), phase of the Precipitation (meteorology), precipitation which is falling to ground level. There are three distinct ways that precipitation can occur. Convective precipitation is generally more intense, and of shorter duration, than stratiform precipitation. Orographic precipitation occurs when moist air is forced upwards over rising terrain and condenses on the slope, such as a mountain. Precipitation can fall in either liquid or solid phases, is mixed with both, or Phase transition, transition between them at the freezing level. Liquid forms of precipitation include rain and drizzle and dew. Rain or drizzle which freezes on contact with a surface within a subfreezing air mass gains the preceding adjective "freezing", becoming the known freezing rain or freezing drizzle. Slush is a mixture of both liquid and solid precipitation. Frozen forms of precipitation include sno ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Taihang Mountains
The Taihang Mountains () are a Chinese mountain range running down the eastern edge of the Loess Plateau in Shanxi, Henan and Hebei provinces. The range extends over from north to south and has an average elevation of ; its principal peak is Mount Xiaowutai. The Taihang's eastern peak is Mount Cangyan in Hebei; Baishi Mountain forms its northern tip. Event * 185 The rebels of the Yellow Turban are defeated by the imperial army, but only two months later, the rebellion breaks out again. It spreads to the Taihang Mountains on the western border of Hebei Province. Background The Taihang Mountains were formed during the Jurassic. Brown forest and Cinnamon soils are found here. The name of Shanxi Province, meaning "west of the mountains", derives from its location west of the Taihang Mountains. The name of Shandong Province (east of the mountains) originally applied to the area east of the Xiao Mountains, but by the Tang dynasty it refers to the area east of the Ta ...
