I am having trouble programming CAPE (Convective Available Potential Energy).
I am designing a weather program in VBA than can, although seemingly impossible, calculate
CAPE values based on ELR temperatures and Parcel Temperatures lifted thermodynamically
from the ground up, without a weather balloon. But when calculated, the program displays CAPE as
a negative number, such as -1400 Joules/Kilogram. If it were positive, it would be correct. What can
be an alternative?

Recheck your equations and make sure all of the signs are correct.

How does one get the lapse rate without a balloon sounding or computer generated sounding?

Just curious.

Is it possible that you have the ELR temperatures and Parcel Temperatures transposed in your equation?

Perhaps you must use absolue value in your calculations......MGC

The formulas I am using are based on a constant known as the average Environmental Lapse Rate. The adiabatic lapse rate for dry air is approximately 5.4 degrees F for every 1000 Ft. in geometric altitude, while the lapse rate for saturated air is roughly 3.6 degrees F every 1000 Ft. The thermodynamics seem different but this is only a hypothetical assumption. I combine weather wisdom along with the true science of meteorology to teach the computer a more statistically accurate weather forecast. If my theory is correct, then I may be able to teach a machine weather instincts. I somehow have been more than 95% accurate in predicting severe weather than the National Weather Service in League City Texas. With more help from experts, I am certain I can achieve success.
