Suppose you are on a journey, starting at the sweltering equator, moving through lush forests, dry deserts, temperate lands, and finally, reaching the icy poles. This is precisely how G.T. Trewartha classified the world’s climates—using temperature and precipitation as the guiding factors, but with a simplified approach compared to Koeppen and Thornthwaite. Unlike Koeppen, who…
Thornthwaite’s climatic classification is more complex and empirical compared to Köppen’s, incorporating evaporation, precipitation efficiency, and potential evapotranspiration (PE) to define climate types. Thornthwaite’s Climatic Classification: A Hydrological Perspective Thornthwaite’s approach introduced a new way of classifying climate, focusing not only on temperature and precipitation but also on evaporation and water balance, making it particularly…
Imagine standing at the equator, where the air is thick with humidity and the forests are lush and green. Now, picture yourself traveling poleward—gradually, the landscape shifts. The dense forests give way to savannas, then to temperate woodlands, followed by cold taigas, and finally, barren icy deserts. This journey across the Earth’s latitudes highlights a…
Suppose you are embarking on a journey across the planet, moving from the lush Amazon rainforest to the icy deserts of Antarctica. As you traverse these diverse landscapes, you’ll notice a striking pattern—each region has a unique climate that influences its vegetation, wildlife, and even human settlements. To make sense of this vast diversity, climatologists…
Imagine standing in an open field when the sky turns an eerie shade of green. Dark clouds swirl above, and suddenly, a towering column of spinning wind descends from the heavens, touching the ground with destructive force—a tornado is born! Tornadoes are among the most violent weather phenomena on Earth. Their winds can exceed 500…
Imagine a summer afternoon in the plains of North India. The sun has been beating down relentlessly, and the air feels thick with humidity. Suddenly, the sky darkens, winds pick up, and within moments, a spectacular display of lightning, deafening thunder, and torrential rain unfolds before you. You have just witnessed the dramatic arrival of…
Let’s say you are standing in the cold, quiet landscape of North India on a winter morning. The sky is clear, the air crisp, and the fields of wheat stand tall, awaiting their lifeline—rain. But unlike the dramatic monsoon showers that arrive with fanfare, this winter rain comes stealthily, carried by an invisible hand from…
Feature Temperate Cyclones 🌍 Tropical Cyclones 🌀 Origin Frontal action (collision of warm and cold air masses) No fronts involved Formation Area Can form over both land and sea Form only over warm ocean waters Size Larger area, covering hundreds of kilometres Smaller in size compared to temperate cyclones Movement Move from west to east…
Naming tropical cyclones makes it easier to communicate warnings, raise awareness, and ensure efficient disaster response. Instead of using long, complicated numbers or scientific terms, short and simple names help the public, meteorologists, and disaster management teams track storms effectively. Who Names Tropical Cyclones? 🌍 There are six Regional Specialised Meteorological Centres (RSMCs) and five…
Tropical cyclones are violent storms that form over warm ocean waters, grow into massive spiralling systems, and unleash destruction upon coastal regions. With wind speeds often exceeding 300 km/h, these storms are among the most powerful natural disasters on Earth. What are Tropical Cyclones? Tropical cyclones are closed low-pressure systems that form between the Tropic…
