Typical atmospheric pressure readings for weather analysis
1Weather Pressure Conversion
Convert between hPa, kPa, inHg, atm, and mmHg for meteorology
Weather Pressure Standards: Meteorologists typically use hPa (hectopascal) or mb (millibar) which are equivalent. Standard sea level pressure is 1013.25 hPa. High pressure systems (greater than 1020 hPa) usually bring clear weather, while low pressure systems (less than 1000 hPa) indicate storms and precipitation.
Weather Pressure Reference
Common pressure ranges and their weather implications
| Pressure (hPa) | Weather Condition | Description |
|---|---|---|
| Greater than 1030 | Very High Pressure | Clear, dry weather, light winds |
| 1020 - 1030 | High Pressure | Clear skies, stable conditions |
| 1013.25 | Standard Pressure | Average sea level pressure |
| 1000 - 1010 | Low Pressure | Cloudy, possible precipitation |
| 980 - 1000 | Very Low Pressure | Stormy weather, strong winds |
| Less than 980 | Extreme Low Pressure | Severe storms, hurricanes |
🌡️ Weather Pressure Tips
- • High pressure (1020+ hPa) typically brings clear, stable weather
- • Low pressure (1000- hPa) indicates unsettled weather and storms
- • Rapid pressure drops often precede severe weather
- • Pressure gradients drive wind patterns and storm systems
- • Meteorologists use pressure maps to predict weather systems
- • Barometric pressure affects human health and animal behavior
