Notes: 1. T - surface temperature - 2 m AGL
2. Tc - convective temperature
3. Tp - thermal deficit (the dufference between the surface temperature and the convective temperature ( T-Tc))
4. Cloud's base and top are determined relative to MSL
5. "*" - unpossible to determine the cloud's type
6. "-" - the cloud's base height is under the ground level
7. Cloudless convection - the height represents the top level. This determines the upper height of instable
atmospheric layer, provided the conditions for development of convective clouds (Cu/Cb) are not satisfied.
8. Fi - Faust index (a (in)stability parameter) [-]
9. SI850 - Showalter Index (a (in)stability parameter) [-]
