 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) [-]
