Légnyomásnál

Légnyomásnál is a Hungarian term that translates to "air pressure" in English. It refers to the force exerted by the weight of the atmosphere on the Earth's surface. This pressure is not uniform across the globe and varies due to several factors, including altitude, temperature, and humidity.

At sea level, standard atmospheric pressure is approximately 1013.25 hectopascals (hPa) or 29.92 inches of mercury. As altitude increases, the density of the air decreases, leading to lower air pressure. Temperature also plays a significant role; warmer air is less dense and exerts less pressure than cooler air. Similarly, moist air is slightly less dense than dry air at the same temperature, resulting in lower pressure.

Changes in légnyomásnál are a key indicator of weather patterns. Rising air pressure generally suggests stable, fair weather, while falling air pressure often precedes stormy or inclement conditions. Meteorologists use barometers to measure air pressure, and these readings are crucial for weather forecasting. Understanding légnyomásnál is fundamental to comprehending atmospheric dynamics and their impact on our daily lives and the global climate.
