What does the CAPE index mean? What does the value in the photo indicate?

The CAPE index quantifies the vertical stability of the atmosphere and the temperature difference between the Earth's surface and higher atmospheric layers. Higher CAPE values typically indicate a greater potential for convective updrafts and the development of thunderstorms.
CAPE is expressed in joules per kilogram (J/kg) and can range from zero to over 5000. In general, CAPE values of less than 1000J/kg represent weak instability, 1000 to 2500J/kg moderate instability, 2500-4000J/kg strong instability, and greater than 4000J/kg extreme instability.

Additionally you can find the definition of CAPE in this page from a “Windy.com sister company” as displayed under its logo :)
