Is Zhaotong air pressure 790 hectopascals high or low?

790 hectopascals, or 790 hectopascals, is a low pressure.

1. In the weather forecast, typhoon centers are all low-pressure areas. A standard atmospheric pressure = 1. 0 13 * 10 5 Pa, that is, 10 13hpa. Below this standard value, it is theoretically low pressure. A standard atmospheric pressure = 10 13 hectopascals, 1002 hectopascals is lower than the standard atmospheric pressure, so it is a low atmospheric pressure. Air pressure is the atmospheric pressure acting on the unit area, that is, it is numerically equal to the gravity of the vertical air column extending upward to the upper limit of the atmosphere.
