Amir, living in the colder region of Kashmir, might find Krishnan’s statement amusing or surprising. To him, 20°C might feel warm or mild, whereas for Krishnan, from warmer Chennai, it feels chilly. This difference shows how people perceive temperature based on what they are accustomed to. Amir might respond by saying, “That’s our summer weather!” or share that in Kashmir, temperatures can fall below 0°C, making 20°C feel like a pleasant day.

When the news reports 30 mm of rainfall, it means that rainwater collected in a rain gauge rose to a height of 30 millimetres. A rain gauge is a cylindrical instrument with a funnel that directs rain into a measuring tube. The depth of water collected indicates the amount of rainfall. It’s a preciseRead more
When the news reports 30 mm of rainfall, it means that rainwater collected in a rain gauge rose to a height of 30 millimetres. A rain gauge is a cylindrical instrument with a funnel that directs rain into a measuring tube. The depth of water collected indicates the amount of rainfall. It’s a precise way to monitor precipitation and helps weather departments track rainy days, issue flood warnings and understand seasonal patterns important for agriculture and water management.

Atmospheric pressure is the force exerted by the weight of air above and around us. It varies with height—being highest at sea level and decreasing with altitude. It influences weather systems; for example, low pressure can lead to storms or rainfall. People often feel changes in pressure before bad weather. It is measured in millibars using barometers. Understanding atmospheric pressure is essential for weather forecasting, flying and even human health, especially in high-altitude regions where oxygen is low.

People feel breathless or tired at high altitudes because the air pressure is lower, which means there is less oxygen available. Our bodies must work harder to absorb oxygen, often resulting in dizziness, fatigue and breathlessness. This condition is more noticeable above 2,500 meters. That's why clRead more
People feel breathless or tired at high altitudes because the air pressure is lower, which means there is less oxygen available. Our bodies must work harder to absorb oxygen, often resulting in dizziness, fatigue and breathlessness. This condition is more noticeable above 2,500 meters. That’s why climbers, tourists and soldiers are advised to acclimatise gradually. Without proper adjustment, one may suffer from altitude sickness, a condition caused by the sudden drop in oxygen levels at higher elevations.

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.
