Flood and Drought Occurrence Drought Drought is a complex, slow-onset phenomenon of ecological challenge that affects people more than any other natural hazards by causing serious economic, social and environmental losses in both developing and developed countries. The period of unusual dryness (i.e. drought) is a normal feature of the Climate and weather system in … Read more
National Atmospheric Research Laboratory (NARL) The National Atmospheric Research Laboratory (NARL) is an autonomous Research Institute funded by the Department of Space of the Government of India. NARL is engaged in fundamental and applied research in the field of Atmospheric Sciences. The research institute was started in 1992 as National Mesosphere–Stratosphere–Troposphere (MST) Radar Facility (NMRF). … Read more
Pressure and wind belts Atmospheric Pressure, also called barometric pressure, force per unit area exerted by an atmospheric column (that is, the entire body of air above the specified area). Atmospheric pressure can be measured with a mercury barometer (hence the commonly used synonym barometric pressure), which indicates the height of a column … Read more
The General Circulation of the Atmosphere: A Symphony of Winds and Weather The Earth’s atmosphere is a dynamic system, constantly in motion, driven by the uneven distribution of solar energy and the planet’s rotation. This movement, known as the general circulation of the atmosphere, is a complex interplay of winds, pressure systems, and temperature gradients … Read more
The Unseen Force: Exploring the World of Tertiary Winds The Earth’s atmosphere is a complex and dynamic system, driven by a delicate balance of energy and forces. While we often focus on the familiar patterns of primary and secondary winds, there exists a lesser-known yet crucial player in this atmospheric ballet: tertiary winds. These winds, … Read more
The Westerlies: A Global Force Shaping Weather and Climate The Earth’s atmosphere is a dynamic system, constantly in motion, driven by the uneven distribution of solar energy. This movement manifests in various forms, including the powerful winds that circle the globe. Among these, the Westerlies, a dominant force in the mid-latitudes, play a crucial role … Read more
The Trade Winds: A Global Force Shaping Climate and History The Earth’s atmosphere is a dynamic system, constantly in motion due to uneven heating from the sun. This dynamic nature gives rise to various wind patterns, one of the most prominent being the trade winds, also known as easterlies. These persistent winds, blowing from east … Read more
Convectional Rainfall: A Deep Dive into the Dynamics of Thunderstorms Convectional rainfall, often associated with dramatic thunderstorms, is a powerful force shaping our weather patterns and influencing ecosystems. This type of precipitation arises from the rapid uplift of warm, moist air, leading to the formation of towering cumulonimbus clouds and intense downpours. Understanding the mechanisms … Read more
Inversion of Temperature: A Phenomenon Shaping Our Atmosphere The Earth’s atmosphere is a complex and dynamic system, constantly in motion and subject to a myriad of influences. One of the most intriguing and impactful phenomena within this system is the inversion of temperature, a condition where the air temperature increases with altitude, defying the typical … Read more
Climatology: Unraveling the Secrets of Earth’s Climate System Climatology, the study of Earth’s climate, is a multifaceted and essential field that delves into the intricate workings of our planet’s atmosphere, oceans, and land surfaces. It encompasses the analysis of long-term weather patterns, the identification of climate change drivers, and the prediction of future climate scenarios. … Read more
