Clouds parameters: BL clouds pct / small cu base / BL overcast / CAPE / precipitation   /  Wind parameters  /  thermal parameters  /  sfc parameters Quick help: Overcast development potential blipmap evaluates the potential for extensive cloud formation (Overcast development = OD) at the BL top. Likely OD is predicted when the parameter is positive, with OD being increasingly more likely with higher positive values. OD can also occur with small negative values over a small-scale ridge not resolved by the model's smoothed topography. This parameter is truncated at -10,000 for plotting. Empirical evaluation of OD Potential predictions vs. actual OD experience and use of an empirical criterion different from zero may yield better results at your location. Note that in some cases only negative numbers may appear in the colorbar legend, in which case we should read that OD becomes increasingly more likely with less negative vales". Aide rapide: On value ici, par des calculs complexes, la possibilit de surdveloppement nuageux dans la couche convective (CC). Plus les plages du domaine ont des couleurs correspondant des valeurs proches ou suprieures zro, plus le surdveloppement y est probable. Les valeurs en dessous de -10000 sont tronques -10000.
