Climate, Soil & Vegetation

  • The Thermal Theory of Monsoon

    The thermal theory was propounded by the British scholars. Dudley Stamp and Baker have played an important role in it. According to this theory, temperature is the main reason of the origin of monsoons. In summer, the sun rays fall perpendicularly in the Northern Hemisphere. The Southern trade winds which generally blow between 300 and 50 South latitudes, cross the Equator because of the Northern move of the thermal equatorial line.

  • The Jet Stream Theory

    The Jet theory was propounded by Yest. The Jet stream is very fast blowing air current system in the upper atmosphere (9 to 18 km). Its speed is maximum (340 km/h) in the middle part. During winter season the upper air westerly jet streams are positioned in Asia. During summer season as sun falls vertically over the Tropic of Cancer the polar surface high pressure is weakened and upper air circum polar whirl shift northward.

  • The Equatorial Westerly Theory

    The Equatorial Westerly Theory has been propounded by Flohn. He thinks of the thermal low of northern India and the accompanying monsoon as simply an unusually great northward displacement of the Northern Inter-Tropical Convergence Zone (NITCZ). The seasonal shift of the ITCZ has given the concept of Northern Inter- Tropical Convergence Zone (NITCZ) in summer (July) and Southern Inter-Tropical Convergence Zone (SITCZ) in winter (Jan.). The fact that the NITCZ is drawn to about 30° latitude may be associated with the unusually high temperature over north India

  • Classification and Properties of the major soil in India

    The soil is formed when rocks are broken down by the action of wind, water and climate. The characteristic features of a soil depend upon the rocks from which it has been formed and the kind of plants that grow in it. In this article, we are giving the classification of the soil, composition of the soil, formation of the soil, distribution of the soil in India and what types of crops grown in the particular soils which is very useful for the UPSC-prelims, SSC, State Services, NDA, CDS, and Railways etc.

  • Do you know the difference between Peninsular River regime and the Himalayan River regime

    The climatic condition of any place or region controlled the flow of the river system. The River Regime is the pattern of the seasonal flow of water in any river. Here, we are giving brief note which will be helpful for understanding the differences between Peninsular River regime and the Himalayan River regime.

  • How does the Tibet Plateau influence the monsoon system of the Indian Subcontinent?

    The monsoon system of the Indian subcontinent has appeared as truly massive interruptions and reversal of the normal global atmospheric circulation, which make it different from the rest of the world. Here, we are giving a brief note on ‘How does the Tibet Plateau influence the monsoon system of the Indian Subcontinent’, which is very useful for competitive examinations like UPSC, SSC and State Services.

  • What are the factors responsible for the formation of Soil?

    The soil is one of the important components of the sustainability of an ecosystem because it is the vitally important natural medium for the growth of vegetation. Here, we are giving brief note on the major factors which are responsible for the formation of the Soil which is very useful for competitive examinations like UPSC, SSC and State Services.

  • Wildlife Sanctuaries and National Parks

    Indian subcontinent is not only well known for its Cultural diversity, but also have a diverse range of flora and fauna. Human activities are permitted in a wildlife sanctuary whereas these are completely restricted in a national park. Hunting is prohibited without permission in a sanctuary; however, grazing and movement of cattle is permitted. Therefore, India houses a number of wildlife sanctuaries and national parks that help in preserving the wildlife in its natural form. Hunting and grazing are totally prohibited in a national park.

  • What are the differences between El Nino and La Nina?

    The El Nino and La Nina are part of the global climate system which occurs when the Pacific Ocean and the atmosphere above it change from their neutral ('normal') state for several seasons. Here, we are giving the differences between El Nino and La Nina on the basis of meaning, Temperature at Sea Surface, Pressure, Trade winds, Seasons, Coriolis force, Ocean waters in the Pacific and cyclone for general awareness.

  • How does El Nino and La Nina impact on Indian Weather?

    The Sea surface temperatures play a major role in global weather which influences two extreme phases of a naturally occurring climate cycle. I.e., El Nino/Southern Oscillation and La Nina. Both terms refer to large-scale changes in sea-surface temperature across the eastern tropical Pacific and the most powerful phenomenon of the Earth. Here, we are giving the write-up on the ‘How does El Nino and La Nina impact on Indian Weather?’ for general awareness.

  • Coastal Erosion in India

    The Coastal Erosion is the process of wearing away of the land by the sea due to corrosion, abrasion, hydraulic action, attrition and corrosion/solution. India's has long peninsular region and due to developmental activities are often carried out without properly understanding the coastal dynamics, leading to long-term damage, particularly to local communities. Find out the concept of Coastal erosion, findings of Ministry of Earth Sciences, and reasons for coastal erosion and measure to deal with coastal erosion for the preparation competitive examination.

  • How the pre-monsoon rain became the boon of India's markets and Farmers!

    India is a land of diverse range of climatic condition ranging from tropical in south, temperate and alpine in the Himalayan region, whereas some part of north-western part remains dry (Thar Desert) and some parts like Sunderban Delta, Andaman and Nicobar Islands and the Gulf of Kutch in Gujarat are characterised by mangrove vegetation. Hence, it very difficult to generalised the India’s diverse geographic level, and its wide range of weather. Let's find out, how pre-monsoon brings blessings and happiness to the India's markets and Farmers.

  • Summary on Climate of India

    The climate of India may be broadly described as tropical monsoon type. The term “monsoon” is derived from Arabic word ‘mausim’ which means seasonal reversal in the wind direction. The Indian Meteorological Department (IMD) designates four official seasons. Here, we are giving the ‘Summary on Climate of India’ which is very useful for the preparation of competitive examinations like UPSC-prelims, SSC, State Services, NDA, CDS, and Railways etc.

  • Report of Red Data Book

    The IUCN (International Union for Conservation of Nature) Red Lists are the bearers of genetic diversity and the building blocks of ecosystems, and information on their conservation status and distribution provides the foundation for making decisions about conserving biodiversity from local to global levels. The IUCN Global Species Programme working with the IUCN Species Survival Commission (SSC) has been assessing the conservation status of species, subspecies, varieties, and even selected subpopulations on a global scale for the past 50 years in order to highlight taxa threatened with extinction, and thereby promote their conservation.

  • Important facts about Wildlife

    Under the agreement of Human Environment Conference 1972 (Stockholm) the Project Tiger was launched in India in 1973 with the help of the World Wide Fund for Nature (WWF). According to the Wildlife Institute of India, Dehradun and the Ministry of Environment and Forests, India, there were only 9 tigers reserved in India during 1973-74 whereas there have been established 41 of them untill January 2013.
