The continental drift theory hypothesis was given by Alfred Wegener in the year of 1912. Wegener said that continents were a single supercontinent. Alfred Wegener proposed single supercontinent name Pangaea, which meaning is all earth in ancient Greek. He told that Pangaea broke up and converted into the continents in their current positions. this hypothesis called the continental drift.
Evidences of Continental Drift
Alfred Wegener Give evidences to support his continental drift theory, he told that identical rocks of the same type and age are found on both sides of the Atlantic Ocean. mountain ranges in eastern Greenland, Ireland, Great Britain, and Norway, formed a single mountain range that was separated by the continents drifted. Ancient fossils of the same species, plants and animals are found of the same age on different continents that are now widely separated.
Naming Of Tropical Cyclones
World Meteorological Organization (WMO) maintains rotating lists for the naming of each Tropical Cyclone basin. If a cyclone is deadly then its name is changed and replaced by another one.
The life of Tropical cyclones can be a week or more, there can be more than one cyclone at a time. so forecasters give each tropical cyclone a name to avoid confusion, tropical cyclones are named according to the rules at regional level. In Indian ocean and South Pacific, tropical cyclones receive names in alphabetical order of women and men's names. in the Northern Indian ocean naming tropical cyclones are listed alphabetically country wise, and are neutral gender wise.
The common rule of naming the Tropical cyclones is that, the name list is proposed by the National Meteorological and Hydrological Services (NMHSs) of WMO Members for a specific region tropical cyclone at their annual/biennual sessions.
Urban Heat Island
Urban Heat Island effect is due to human factors induced higher temperatures 8 to 10 degrees more in urban areas compared to the temperatures in rural areas. Due to Urban Heat Island effect in urban areas needs more power, air conditioner produce greenhouse gas emissions and polutes the air, which results the heat related illness and mortality.
Reason of Urban Heat Island effect
There are many reasons of Urban Heat Island effect in the cities like high use of construction materials like Asphalt and concrete, high rise buildings with dark surfaces, air conditioning, mass transportation fossil fuels vehicle and lack of trees and green park. To reduce Urban Heat Island we should planning smart cities with high number of trees.
In the normal conditions of atmosphere, temperature usually decreases with increase in altitude in the troposphere. but due to horizontal or vertical movement of air the normal behavior of temperature in the troposphere get reversed, and temperature starts increasing with height rather than decreasing. This is called temperature inversion. Favourable Conditions for Temperature Inversion are Long winter nights, Cloudless and clear sky, Dry air near the ground surface, Slow movement of air and Snow covered ground surface.
Effects Of Temperature Inversion
The effects of Temperature inversion are the precipitation, forms of clouds, more dust particles in the air, Stops the movement of air, Lower visibility, Thunderstorms and tornadoes.
