Published	05/30/2023	Define Squall
Published	05/30/2023	Define Pressure Gradient force
Published	05/30/2023	The bigger the pressure difference the {{c1::greater the force}} (pressure) on the air to move,
Published	05/30/2023	closer the isobars ({{c1::steep}}) → the smaller the distance → the {{c1::stronger the wind}} speed (greater PGF)
Published	05/30/2023	Greater distance between Isobars indicate a {{c1::slack PGF}} gradient and therefore {{c1::slower wind}} speed.
