Întrebare. Unde apare plaflonul de nori (alt minimă, maximă) într-o citire de sondaj atmosferic?
Baza plafonului o poti estima foarte bine dupa - LCL - Lifted Condensation Level - Nivelul de Condensare prin Ascendenta
LCLP - Pres [hPa] of the Lifted Condensation Level -presiunea in hectopascali a nivelului de consensare prin ascendenta
LCLP este un bun indicator a bazei norilor. Il gasesti mai jos.
Poti estima plafonul pe baza umiditatii sau a punctului de roua + temperatura. Unde aerul este aproape de saturatie cam acolo sunt nori.
Din sondajul postat de mine mai sus as zice ca poti aproxima ca plafonul de stratusi ajungea la peste 800 m deasupra Bucurestiului.
