It is the summer season in the Southeast United States and convective activity is expected during the afternoon. Use the 1200 UTC sounding below to forecast the turbulence intensity in and around the convection that develops later in the day.
Use the Eastern Airlines Method to determine the turbulence intensity.
Answer: Delta-T is approximately 7°C (see graphic).
From the CCL, proceed upward along a moist adiabat to 400 hPa, where parcel
temperature (T')=-18°C and the sounding temperature (T) is -25°C.
Therefore:
Delta-T = T'-T = (-18) - (-25) = 7°C.
What turbulence intensity would you expect?
