The Intergovernmental panel on climate change (IPCC) latest report says that climate change is a grave and mounting threat to our wellbeing and a healthy planet. The actions today will shape how people adapt and nature responds to increasing climate risks. The IPCC Working Group II report, Climate Change 2022: Impacts, Adaptation and Vulnerability was … Read more
The Ministry of Environment, Forest and Climate Change recently released the State of Forest Report 2021. It is called the ISFR, 2021. The report says that there has been a continuous growth of forest cover in India. The current forest cover of India is 7,13,789 square kilometres. In the last two years, the forest … Read more
The minimum support price’s (MSP) tilt in favour of oilseeds has shown results with the acreage of mustard reporting a 23% increase this year, so far, over its sown area in the corresponding period last year. It is expected to increase a bit further as sowing in the ongoing Rabi (winter crop) season continues till the end … Read more
The National Perspective Plan (NPP) was prepared by the then Ministry of Irrigation (now Ministry of Jal Shakti) in August 1980 for water resources development through inter basin transfer of water, for transferring water from water surplus basins to water-deficit basins. Under the NPP, the National Water Development Agency (NWDA) has identified 30 links (16 … Read more
. The interplay of the wind and the monsoon system combined with the Earth system produces these synchronous cyclones.The twin tropical cyclones are caused by what are called equatorial Rossby waves This system has a vortex in the northern hemisphere and another in the southern hemisphere, and each of these is a mirror image of … Read more
Cyclones are also termed atmospheric disturbances. When the velocity of winds increases to such an extent that they attain strong force, a cyclonic storm is formed. Cyclones are the centres of low pressure. They are surrounded by closed isobars having increasing pressure outward. The wind circulation is from outside towards the central low pressure. They … Read more
Anticyclones are centres of high pressure.They are surrounded by closed isobars having decreasing pressure outward. The circulation is from central high pressure towards the periphery in such a way that air blows outwards in a clockwise direction in the Northern hemisphere and anticlockwise direction in the southern hemisphere. Due to Coriolis force, blowing winds are … Read more
. It is an inclined zone along which two opposing air masses having contrasting characteristics in terms of air temperature humidity density pressure converged together. An extensive transitional zone between two converging air masses is called a frontal zone. The frontal zone is inclined at a low angle to the Earth’s surface. It is also … Read more
Air mass is a large body of air having little horizontal variation in temperature and moisture.The air masses have a relatively uniform distribution of vertical gradients in their physical properties like temperature, pressure, and humidity. Air masses are formed in very particular surface and atmospheric conditions which are found only in a few areas of … Read more
Cyclonic rain occurs due to the convergence of extensive air masses. When two contrasting air masses like cold polar air mass and warm westerly air mass coming from opposite directions converge along a line a front is formed. The warm wind is lifted upward along this front where the cold air being heavier settles down. … Read more
