Climates of Nepal with glimpse on Post Monsoon

Nepal is a small landlocked country located between world’s two most populous countries China to the north and India to the east, west and south with a total land area of 147,181 sq km. Nepal stretches from 26º 22’ to 30º 27’ North latitude and from 80º 04’ to 88 º 12’ East longitudes. The country looks roughly rectangular in shape with the length from east to west of about 885 km and width ranging from 130 to 260 km. The elevation of the country increases from about 60 m above mean sea level in the south to more than 8800 m above mean sea level in the north. The highest peak Mt. Everest, known as Sagarmatha to the Nepalese, rises to 8848 m and lies at the northern part of east Nepal . The country is divided into three broad ecological regions, i) the mighty Himalayas in the north, ii) Hills and Valleys in the middle, and iii) Terai, an extension of Indo-Gangetic plain, in the south. Mountains, Hills and the Terai regions are homes to 7 %, 46 % and 47 % of Nepal’s populati

A POLAR VORTEX

Glimpse: A low-pressure area with a wide expansion of swirling cold air surrounding both Polar Regions where counter-clockwise flow of air helps keep the colder air near the poles. 2. Polar vortex event: In winter, in the northern hemisphere the polar vortex sometimes becomes less stable and expands i.e. Breaking off” of a part of the vortex, sending cold air southward with the jet stream. 3. Normal case: When the vortex is strong and healthy, it helps keep a current of air known as the jet stream traveling around the globe in a pretty circular path. This current keeps the cold air up north and the warm air down south. 4. Opposite case: Without the strong low-pressure system, the jet stream becomes wavy and rambling. Put a couple of areas of high-pressure systems in its way, and all of a sudden a river of cold air being pushed down south along with the rest of the polar vortex system. 5. Though the polar vortex is always “hanging out” up North,

Cyclone Name like Tauktae, Yaas, Gulab & so on

So far two intense cyclones has formed, named "Tauktae" and "Yaas", over Northern Indian Ocean . T ropical cyclone observation has been carried out over the past couple of centuries in various ways. The passage of typhoons, hurricanes, as well as other tropical cyclones have been detected by word of mouth from sailors recently coming to port or by radio transmissions from ships at sea, from sediment deposits in near shore estuaries, to the wiping out of cities near the coastline. Since World War II , advances in technology have included using planes to survey the ocean basins, satellites to monitor the world's oceans from outer space using a variety of methods, radars to monitor their progress near the coastline, and recently the introduction of unmanned aerial vehicles to penetrate storms. Recent studies have concentrated on studying hurricane impacts lying within rocks or near shore lake sediments, which are branches of a new field known as paleotempestolog
