The atmosphere is a blanket of gases surrounding Earth, composed mainly of nitrogen and oxygen. It plays a vital role in sustaining life by providing oxygen, regulating temperature and shielding Earth from harmful solar radiation. The lowest layer, called the troposphere, is where all weather events occur and where we live and breathe. The atmosphere helps maintain Earth’s temperature, allows cloud formation and enables rain, snow and winds—making it essential for life on Earth.

Accurate weather measurements allow better planning in various sectors. Farmers use forecasts to decide when to plant or harvest crops. Pilots and sailors depend on wind and pressure data for safe travel. Weather updates help people plan outings or events and avoid risks. Health services use heatwave data to issue alerts. Disaster management agencies need early warnings to prepare for floods or storms. Tourism, construction and transportation all benefit from reliable weather data.

Meteorology is the scientific discipline that studies weather patterns and atmospheric conditions. It focuses on understanding how weather changes over time by measuring elements like temperature, humidity, wind speed and air pressure. Meteorologists collect and analyze data using special instruments to forecast weather. These forecasts help people prepare for daily activities or extreme events like storms and droughts. Meteorology is essential for agriculture, aviation, disaster management and other sectors that rely on weather predictions.

Elders use signs in nature to forecast weather. Common observations include ants carrying eggs before rain, frogs croaking loudly, birds flying low or the sky turning red at sunset. These signs, passed down for generations, help communities prepare for rain or storms. Local sayings, like “Kaale badal aaye, to baarish pakki hai” (If black clouds gather, rain is sure), are part of this wisdom. Such folk knowledge is still used in rural areas without access to forecasts.

Rain is indirectly caused by the sun. The sun’s heat warms water bodies like oceans, rivers and lakes, turning water into vapour through evaporation. This vapour rises into the cooler parts of the atmosphere, condenses into clouds and later falls as rain. Thus, without sunlight, the evaporation-condRead more
Rain is indirectly caused by the sun. The sun’s heat warms water bodies like oceans, rivers and lakes, turning water into vapour through evaporation. This vapour rises into the cooler parts of the atmosphere, condenses into clouds and later falls as rain. Thus, without sunlight, the evaporation-condensation-rainfall cycle wouldn’t occur. This is why ancient texts rightly say “From the sun arises rain.” The sun powers the water cycle, which brings essential rainfall to Earth.
