A typical day’s change through the year
Each date of the year has its own bar. The taller the bar, the bigger a typical day’s change around that date.
Does the pressure change a lot in Jingzhou?
Jingzhou has more days with a change of more than 10 hPa than 60 out of every 100 large cities.
Each dot stands for up to 20 cities with 100,000 people or more. The first column is much taller than shown. Cities higher than 1,000 m are left out, and so are smaller cities within 15 km of a bigger one, unless they are capitals, so that suburbs are not counted twice.
These figures come from ERA5, in which the European weather centre ECMWF rebuilds past weather from a weather model and observations, for an area about 28 km across around Jingzhou, 1991 to 2020. Each change is the difference between one day’s average pressure and the next day’s.

Is the barometer rising or falling in Jingzhou today?

What has the pressure in Jingzhou been over the last few days?
Over the past 7 days it ran between 1011 hPa (this afternoon) and 1023 hPa (on Tuesday morning). The biggest change in any 24 hours was a rise of 6 hPa, in the 24 hours ending on Tuesday morning.
Is 1012 hPa high or low pressure?
Atmospheric pressure between about 1000 and 1025 hPa is ordinary at sea level. 1012 hPa sits in the middle of that range. In Jingzhou most days average between 1001 and 1031 hPa. The last 24 hours average about 1014 hPa, within that usual range.
What is normal barometric pressure for Jingzhou?
From 1991 to 2020 the sea-level average for Jingzhou was 1015 hPa, and most days average between 1001 and 1031 hPa. It is usually highest in December and January and lowest in July.
When does barometric pressure change the most in Jingzhou?
The pressure in Jingzhou changes most in March. Between 1991 and 2020, Jingzhou had about 5 days a year with a big change, of more than 10 hPa from one day to the next.
Why does my own barometer show a different number?
Usually altitude, and sometimes the instrument itself. To compare cities, pressure is corrected to sea level. The figure for Jingzhou, which stands 38 m above sea level, is in the note above: about 4 hPa below the sea-level reading. If your barometer is already set to sea level and still reads slightly differently, that is the setting on the instrument rather than the weather.
Does falling pressure mean rain?
Not by itself. Away from the tropics, falling pressure usually means a low is approaching, and lows carry the fronts that bring cloud and rain, so the two often arrive together. But a shallow fall can pass with nothing more than cloud, and rain falls under steady pressure too. The graph tells you a system is on the way, not how wet it will be. The week ahead, just above, shows the rain forecast beside the pressure.
