Concept of pressure Pressure is the perpendicular force per unit area, or the Stress at a point within a confined fluid. The pressure exerted on a floor by a 42-pound box the bottom of which has an area of 84 square inches is equal to the force divided by the area over which … 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

SDO is a NASA mission launched on February 11, 2010 which will observe the sun for over five years. The observatory is a part of the living with a star program. SDO’s goal is to understand the sun’s influence on earth and near-earth space by studying the solar Atmosphere on small scales of space and … 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 Unseen Force: Pressure Gradient and Its Role in Air Circulation The Earth’s atmosphere is a dynamic system, constantly in motion. This movement, known as air circulation, is driven by a fundamental force: the pressure gradient. Understanding this force is crucial to comprehending weather patterns, climate variations, and even the global distribution of heat and … 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
The Invisible Force: Understanding Humidity and Its Impact on Our World Humidity, an often-overlooked aspect of our environment, plays a crucial role in shaping our world. From influencing weather patterns to impacting human health and comfort, humidity is a powerful force that deserves our attention. This article delves into the intricacies of humidity, exploring its … Read more
