EVERYDAY SCIENCE

Detailed explanation-1: -Generally, a rising barometer tells us that the weather is improving. Also, the decreasing barometer indicates that the weather is getting worse. When the air pressure suddenly lowers, it usually means a storm is approaching. There will most likely be no immediate change in the weather if air pressure remains constant.

Detailed explanation-2: -In general, a falling barometer means worsening weather. When atmospheric pressure drops suddenly, this usually indicates that a storm is on its way. When atmospheric pressure remains steady, there will likely be no immediate change in the weather.

Detailed explanation-3: -Simply put, barometric pressure is the measurement of air pressure in the atmosphere, specifically the measurement of the weight exerted by air molecules at a given point on Earth.

Detailed explanation-4: -A low pressure system has lower pressure at its center than the areas around it. Winds blow towards the low pressure, and the air rises in the atmosphere where they meet. As the air rises, the water vapor within it condenses, forming clouds and often precipitation.

Detailed explanation-5: -Thus, higher pressure is indicative of calm weather, while low barometric pressure indicates poor weather. Meteorologists and sailors use fluctuations in barometric pressure to forecast weather conditions.
