The chart shows you the temperature along the left axis and the humidity is on the top. The numbers that run between the two axis are the vapor pressure deficit numbers.

Vapor pressure acts equally in all directions and affects the entire low or high side of a refrigeration system. As pressure increases, saturation temperature increases. As pressure decreases, so does ...

The hot, humid exhaust from jet engines mixes with the atmosphere, which at high altitude is of much lower vapor pressure and temperature than the exhaust gas.
