Atmospheric pressure is crucial for weather prediction. A sudden drop can indicate storms, depressions or cyclones. That’s why meteorologists monitor pressure regularly. Pilots rely on it for flight safety, sailors for sea navigation and mountaineers for health monitoring at high altitudes. Even farmers benefit, as pressure data helps forecast rain or dry spells. Barometers measure this pressure, often recorded in millibars. Accurate readings are essential for disaster warnings, aviation safety and overall weather forecasting.

When people travel to high altitudes, air pressure drops and oxygen levels decrease. The body needs time to adapt by producing more red blood cells to carry oxygen. Taking breaks along the way allows this process, known as acclimatisation, to occur. Without this adjustment, individuals may experience altitude sickness—symptoms include dizziness, headaches and nausea. Hence, trekkers, tourists and soldiers climbing high passes like Khardung La pause often to protect their health and avoid severe discomfort.

Many seeds, such as those from cotton or dandelions, are light and have special structures that help them float in the wind. This wind dispersal helps them travel far from the parent plant, reducing competition. If there were no wind, these seeds would drop nearby, causing overcrowding and limitingRead more
Many seeds, such as those from cotton or dandelions, are light and have special structures that help them float in the wind. This wind dispersal helps them travel far from the parent plant, reducing competition. If there were no wind, these seeds would drop nearby, causing overcrowding and limiting space, sunlight and nutrients. Dispersal by wind is essential for spreading plant species and supporting biodiversity. It ensures plants grow in different areas, supporting forest and grassland expansion.

A wind sock is a fabric tube shaped like a cone and used to indicate wind direction and relative strength. It is often seen at airports, on runways and in industrial areas.

A wind sock is a fabric tube shaped like a cone and used to indicate wind direction and relative strength. It is often seen at airports, on runways and in industrial areas. When the wind blows, the sock points away from the wind’s origin, allowing observers to determine the direction. The stronger the wind, the straighter the sock stands. Wind socks are crucial for aviation, ensuring pilots know wind conditions before takeoff and landing.
