Climate Of Vietnam
Vietnam has a monsoon-influenced climate typical of that of mainland Southeast Asia. The diverse topography, long latitude (Vietnam spans over 15° of latitude), and influences from the South China Sea lead to climatic conditions varying significantly between regions. The northern region experiences a monsoonal and temperate climate (Cfa) with four distinct seasons (spring, summer, autumn, and winter) with winters typically dry and summers ranging from hot to mild. In more southern areas, the climate is tropical monsoon (Aw) with only two seasons (rainy and dry). In addition, a temperate climate exists in mountainous areas, which are found in Sa Pa and Da Lat, while a more continental climate exists in Lai Châu Province and Sơn La Province. 20% of Vietnam's total surface area is low-elevation coastal area, making the country highly vulnerable to climate change effects and the rising sea levels in particular.

Mainland Southeast Asia
Mainland Southeast Asia, also known as the Indochinese Peninsula or Indochina, is the continental portion of Southeast Asia. It lies east of the Indian subcontinent and south of Mainland China and is bordered by the Indian Ocean to the west and the Pacific Ocean to the east. It includes the countries of Cambodia, Laos, Myanmar, Thailand and Vietnam, with peninsular Malaysia sometimes also being included. The term Indochina (originally Indo-China) was coined in the early nineteenth century, emphasizing the historical cultural influence of culture of India, Indian and Chinese culture, Chinese civilizations on the area. The term was later adopted as the name of the colony of French Indochina (today's Cambodia, Laos, and Vietnam). Today, the term, Mainland Southeast Asia, in contrast to Maritime Southeast Asia, is more commonly referenced. Terminology The origins of the name Indo-China are usually attributed jointly to the Danish-French geographer Conrad Malte-Brun, who referre ...

Snowfall In Sa Pa
Snow comprises individual ice crystals that grow while suspended in the atmosphere—usually within clouds—and then fall, accumulating on the ground where they undergo further changes. It consists of frozen crystalline water throughout its life cycle, starting when, under suitable conditions, the ice crystals form in the atmosphere, increase to millimeter size, precipitate and accumulate on surfaces, then metamorphose in place, and ultimately melt, slide or sublimate away. Snowstorms organize and develop by feeding on sources of atmospheric moisture and cold air. Snowflakes nucleate around particles in the atmosphere by attracting supercooled water droplets, which freeze in hexagonal-shaped crystals. Snowflakes take on a variety of shapes, basic among these are platelets, needles, columns and rime. As snow accumulates into a snowpack, it may blow into drifts. Over time, accumulated snow metamorphoses, by sintering, sublimation and freeze-thaw. Where the climate is cold ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Insolation
Solar irradiance is the power per unit area ( surface power density) received from the Sun in the form of electromagnetic radiation in the wavelength range of the measuring instrument. Solar irradiance is measured in watts per square metre (W/m2) in SI units. Solar irradiance is often integrated over a given time period in order to report the radiant energy emitted into the surrounding environment (joule per square metre, J/m2) during that time period. This integrated solar irradiance is called solar irradiation, solar exposure, solar insolation, or insolation. Irradiance may be measured in space or at the Earth's surface after atmospheric absorption and scattering. Irradiance in space is a function of distance from the Sun, the solar cycle, and cross-cycle changes.Michael Boxwell, ''Solar Electricity Handbook: A Simple, Practical Guide to Solar Energy'' (2012), p. 41–42. Irradiance on the Earth's surface additionally depends on the tilt of the measuring surface, the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Typhoons
A typhoon is a mature tropical cyclone that develops between 180° and 100°E in the Northern Hemisphere. This region is referred to as the Northwestern Pacific Basin, and is the most active tropical cyclone basin on Earth, accounting for almost one-third of the world's annual tropical cyclones. For organizational purposes, the northern Pacific Ocean is divided into three regions: the eastern (North America to 140°W), central (140°W to 180°), and western (180° to 100°E). The Regional Specialized Meteorological Center (RSMC) for tropical cyclone forecasts is in Japan, with other tropical cyclone warning centers for the northwest Pacific in Hawaii (the Joint Typhoon Warning Center), the Philippines, and Hong Kong. Although the RSMC names each system, the main name list itself is coordinated among 18 countries that have territories threatened by typhoons each year. Within most of the northwestern Pacific, there are no official typhoon seasons as tropical cyclones form t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tropical Cyclone
A tropical cyclone is a rapidly rotating storm system characterized by a low-pressure center, a closed low-level atmospheric circulation, strong winds, and a spiral arrangement of thunderstorms that produce heavy rain and squalls. Depending on its location and strength, a tropical cyclone is referred to by different names, including hurricane (), typhoon (), tropical storm, cyclonic storm, tropical depression, or simply cyclone. A hurricane is a strong tropical cyclone that occurs in the Atlantic Ocean or northeastern Pacific Ocean, and a typhoon occurs in the northwestern Pacific Ocean. In the Indian Ocean, South Pacific, or (rarely) South Atlantic, comparable storms are referred to simply as "tropical cyclones", and such storms in the Indian Ocean can also be called "severe cyclonic storms". "Tropical" refers to the geographical origin of these systems, which form almost exclusively over tropical seas. "Cyclone" refers to their winds moving in a circle, whirling ...

Annamite Range
The Annamite Range or the Annamese Mountains (french: Chaîne annamitique; lo, ພູ ຫລວງ ''Phou Luang''; vi, Dãy (núi) Trường Sơn) is a major mountain range of eastern Indochina, extending approximately through Laos, Vietnam, and a small area in northeast Cambodia. The mountain range is also referred to variously as Annamese Range, Annamese Mountains, Annamese Cordillera, Annamite Mountains and Annamite Cordillera. The name "Annam" is the Vietnamese pronunciation and terminology of zh, c=安南 (Pinyin: ''Ān Nán''), meaning "to pacify the south" referring to Vietnam. The French adopted the word and used "Annamese" or "Annamite" to refer to the Vietnamese. The highest points of the range are the -high Phou Bia, the -high Phu Xai Lai Leng and the -high Ngọc Linh (Ngoc Pan). The latter is located at the northwestern edge of the Triassic Kontum Massif in central Vietnam. Important mountain passes are the Nape Pass and the Mụ Giạ Pass. The Annamite ...

Bay Of Bengal
The Bay of Bengal is the northeastern part of the Indian Ocean, bounded on the west and northwest by India, on the north by Bangladesh, and on the east by Myanmar and the Andaman and Nicobar Islands of India. Its southern limit is a line between Sangaman Kanda, Sri Lanka, and the north westernmost point of Sumatra, Indonesia. It is the largest water region called a bay in the world. There are countries dependent on the Bay of Bengal in South Asia and Southeast Asia. During the existence of British India, it was named as the Bay of Bengal after the historic Bengal region. At the time, the Port of Kolkata served as the gateway to the Crown rule in India. Cox's Bazar, the longest sea beach in the world and Sundarbans, the largest mangrove forest and the natural habitat of the Bengal tiger, are located along the bay. The Bay of Bengal occupies an area of . A number of large rivers flow into the Bay of Bengal: the Ganges– Hooghly, the Padma, the Brahmaputra– Yamuna, t ...

Block (meteorology)
Blocks in meteorology are large-scale patterns in the atmospheric pressure field that are nearly stationary, effectively "blocking" or redirecting migratory cyclones. They are also known as blocking highs or blocking anticyclones.Glossary of Meteorology, Second Edition; American Meteorological Society, 2000; . These blocks can remain in place for several days or even weeks, causing the areas affected by them to have the same kind of weather for an extended period of time (e.g. precipitation for some areas, clear skies for others). In the Northern Hemisphere, extended blocking occurs most frequently in the spring over the eastern Pacific and Atlantic Oceans. Whilst these events are linked to the occurrence of extreme weather events such as heat waves, particularly the onset and decay of these events is still not well captured in numerical weather forecasts and remains an open area of research. Impact of the polar vortex Polar cyclones are climatological features which hover ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tibetan Plateau
The Tibetan Plateau (, also known as the Qinghai–Tibet Plateau or the Qing–Zang Plateau () or as the Himalayan Plateau in India, is a vast elevated plateau located at the intersection of Central, South and East Asia covering most of the Tibet Autonomous Region, most of Qinghai, western half of Sichuan, Southern Gansu provinces in Western China, southern Xinjiang, Bhutan, the Indian regions of Ladakh and Lahaul and Spiti (Himachal Pradesh) as well as Gilgit-Baltistan in Pakistan, northwestern Nepal, eastern Tajikistan and southern Kyrgyzstan. It stretches approximately north to south and east to west. It is the world's highest and largest plateau above sea level, with an area of (about five times the size of Metropolitan France). With an average elevation exceeding and being surrounded by imposing mountain ranges that harbor the world's two highest summits, Mount Everest and K2, the Tibetan Plateau is often referred to as "the Roof of the World".
