How quickly can barometric pressure change?


Pnder pressure

Recommended Posts

Hello all,

I’m new to the forum, so I hope I’m not breaking any rules by posting here. I did have a look through the other posts to see if the question had been asked before.

I’m an engineering student working on a project with drones, and I’m trying to solve a height calculation problem using barometric pressure sensors. I know that the barometric pressure changes over time at a given altitude and location, but I’m struggling to find reliable information about how quickly it changes.

I would like to know how quickly the pressure can change within reason (not an approaching hurricane). A likely scenario could be a nice summer day with an approaching storm. I'm interested in the rate of change over short time periods, pascals per minute or per second for example.

I would be very grateful if any meteorologists could share their experience here or point me in the direction of some good data sets.

Thanks in advance

I'd say a rough value would be a few hPa (few hundred Pa) per hour.

Here's a good resource to download ASOS data from a variety of sites around the world. https://mesonet.agron.iastate.edu/request/download.phtml

I suppose this might be a little late for your project, but you may find it helpful for future reference.
