13
Q

kaj se zgodi ce je vlage prevec

A

vlaga kondenzira, zrak nasičen
to se zgodi pri rosiscu

Q

adiabatno segrevanje zraka

A

zrak se pri dvigovanju siri in ohlaja, pri spuscanju se segreva in stiska

16
Q

kje je zracni tlak nizji

A

v visinah

17
Q

kondenzacijski nivo

A

dolocena visina, kjer pride do kondenzacije vlage

18
Q

pogoji za nastanek padavin

A
  1. ohlajanje do rosisca
  2. kondenzacija
  3. porast kapljic
19
Q

orografske padavine

A

nastanejo na privetrnih straneh orografskih ovir
gorske pregrade ovirajo prehod vlaznega zraka in ga prisilijo k dvigovanju (zato se ohladi in nastanejo padavine)

20
Q

padavinska senca

A

obmocje na zavetrni strani orografskih pregrad ki ne preje padavin

21
Q

konvekcijske padavine

A

nastanejo tam kjer prihaja do vertikalnega dviganja zraka
to se dogaja ob hitrem in neenakomernem segrevanju povrsja
tropski pas
adiabatno ohlajanje
dviganje zraka v obliki mehurckov

22
Q

ciklonske padavine

A

nastanejo znotraj ciklonov ob orehodu tople ali hladne fronte
gladen zrak zaradi vecje gostote izpodriva toplega ki se dvigne in ohladi- nastanejo padavine
