Air full form in upsc

The Earth’s atmosphere is made up of a combination of gases called air. A set of gases with virtually constant concentrations and a group of gases with concentrations that vary in both location and time make up the mixture. Consistent concentrations of atmospheric gases (and their proportions in percentage by volume) Mixing associated with atmospheric motions keeps the composition uniform; but, above a height of about 90 km (55 miles), diffusional processes take over, and lighter gases (hydrogen and helium in particular) become more numerous. Airglow Airglow is a weak illumination in the upper atmosphere created by the selective absorption of solar ultraviolet and X-rays by air molecules and atoms. Most of the airglow comes from a range between 50 and 300 kilometres (31 and 180 miles) above Earth’s surface, with the brightest area concentrating at heights around 97 kilometres (60 miles). Unlike the aurora, airglow does not have arcs and is released from the entire sky at all times and at all latitudes. Nightglow is a nighttime phenomenon. The words dayglow and dusk glow are interchangeable. Characteristics of Air Air can be compressed as a gas, which means the molecules can be moved closer together. The air will expand indefinitely to fill the area available if no force compresses it. The volume occupied by a particular amount of gas differs depending on its temperature and pressure. This knowledge leads to a number of useful standard values when working with air. The firs...

In meteorology, an air mass is a vast body of air with essentially consistent temperature and humidity conditions at any given altitude. The limits of such a mass are defined, and it can span hundreds or thousands of kilometres horizontally and as high as the troposphere’s top (about 10–18 km [6–11 miles] above the Earth’s surface). The temperature and moisture properties of a large, reasonably homogeneous land or sea surface are acquired when the atmosphere comes into contact with it over a long enough period of time. The beginnings of the Earth’s major air masses are at polar or subtropical latitudes. The middle latitudes are essentially a zone of polar and tropical air mass alteration, interaction, and mixing. Categorisation of Air Masses Air masses are traditionally classified into four basic source regions based on latitude. Polar (cold), Arctic (very cold), Equatorial (warm and humid), and Tropical (warm). Continental Polar, maritime Polar, continental Tropical, and maritime Tropical are the most common air mass types in the United States. Air Mass Categorisation of the USA Continental Polar (cP): Continental Polar (cP) air occurs across large land areas such as Central Asia and northern Canada during the colder months of the year. It’s most likely stable, and it’s usually free of condensation forms. This type of air mass creates limited convective stratocumulus cloud formations with scattered light rain or snow showers when heated or moistened from the ground with s...

Many people, with the determination to crack the toughest recruitment exam in the world, UPSC, seek coaching and dedicate their time and effort to solely focus on the preparation for UPSC Civil Services Exam. Among the millions of aspirants, we will talk about Sarjana Yadav today. Sarjana Yadav hails from Delhi and completed her engineering from the Delhi Technological University (DTU). Post graduation, she started working as a research officer in TRAI. Even though working, Yadav was determined to crack the UPSC exam and become an IAS officer. Read: In an interview, Sarjana said that it depends on the desire of the candidate whether he/she wants to take coaching or not. "If you think that you have complete study material and your strategy for UPSC is better, then you can also get success by relying on self-study," she said. In 2018, Sarjana decided to dedicate her complete time and energy to the preparations and left her job in 2018.

Tags: • • • • The System of Air Quality and Weather Forecasting And Research (SAFAR) is a national initiative introduced by the Ministry of Earth Sciences (MoES) to measure the air quality of a metropolitan city, by measuring the overall pollution level and the location-specific air quality of the city. • The system is indigenously developed by the Indian Institute of Tropical Meteorology (IITM), Pune and is operationalized by the India Meteorological Department (IMD). • It has a giant true color LED display that gives out real-time air quality index on a 24x7 basis with color-coding (along with 72 hours advance forecast). • The ultimate objective of the project is to increase awareness among the general public regarding the air quality in their city so that appropriate mitigation measures and systematic action can be taken up. • It organizes awareness drive by educating the public (prompting self-mitigation), and • It also helps the policy-makers to develop mitigation strategies keeping in mind the nation’s economic development. • SAFAR is an integral part of India’s first Air Quality Early Warning System operational in Delhi. • It monitors all weather parameters like temperature, rainfall, humidity, wind speed, and wind direction, UV radiation, and solar radiation. • Pollutants monitored: PM2.5, PM10, Ozone, Carbon Monoxide (CO), Nitrogen Oxides (NOx), Sulfur Dioxide (SO2), Benzene, Toluene, Xylene, and Mercury. • The World Meteorological Organization has recognized SAFA...

The competition for the CSE is becoming fiercer every year. Over the last 3-4 years the number of applicants has hovered around 1,000,000 out of which approximately 500,000 appear for the Preliminary Exam. On an average 10,000 candidates qualify for the Mains Examination and less than 2,500 are called for the Personality Test. Finally, only about 1,000 or less candidates qualify to be part of the Services.
