Amamephu afanayo

El imephu yokuvumelanisa , Ama-isobars ahambelana nemigqa yengcindezi elinganayo adonselwa izazi zezulu njalo ngama-hectopascals ama-4 kuzinsizakalo zezulu kwamanye amazwe (isithombe esiphezulu) nawo wonke ama-hectopascals ama-5 kwamanye (isithombe esingezansi). Ngaphandle kwe- isobars ishadi likhombisa izinhlelo ezingaphambili nezikhungo ezinengcindezi ephezulu naphansi.

Manje ake sibheke izinto ezithile eziyisisekelo ezingabonakala kumamephu wokuvumelanisa:

1. Abakwa-Isobars

Zihambisana nemigqa ehlanganisa amaphuzu wengcindezi elinganayo yomkhathi. Inani le- ingcindezi yasemkhathini leyo emele ngayinye yazo ikhonjisiwe kulayini. Isibonelo, ebalazweni elimnyama nelimhlophe inani le-isobar eliwela iziqhingi zaseBalearic lingu-1025 Hpa.

2. Izikhungo Zokucindezela Okuphansi

Zihambelana nokuhlelwa kwama-isobar cishe okuyindilinga ezungeze isikhungo lapho umfutho womoya ukhona okuncane. Imvamisa zimakwa ngezinhlamvu B (squall) noma L (press low), futhi ne-T. Zivame ukuhlotshaniswa nezimo zezulu ezimbi, nezimvula neziphepho.

3. Izikhungo Zokucindezela Okuphezulu

Zihambisana nokuhlelwa kwama-isobar cishe okuyindilinga ezungeze isikhungo lapho umfutho womoya ukhona esiphezulu. Kumakwe nge-A (umfutho ophakeme) noma u-H (umshini ophakeme). Ngokuvamile kuhlotshaniswa nesimo sezulu esihle.

4. Izimpi Ezibandayo

Kumakwe imigqa emangelengele ngombala oluhlaza okwesibhakabhaka, akhombisa ukuthuthuka kwenqwaba ye- Umoya obandayo lokho kubangela imvula ejwayelekile kanye nokwehla kwamazinga okushisa ngemuva kwayo.

5. Izimpi Ezifudumele

Imakwe yimigqa enqunywe ngamasondo anombala obomvu, akhombisa ukuqhubeka kwenqwaba ye- umoya ofudumele lokho kubanga imvula bese kuphakama amazinga okushisa ngemuva kwayo.

6. Izimpi Ezihlangene

Ikhonjiswe ngengxube yezimpawu zangaphambili ezifudumele nenye engaphambili ebandayo nensomi. Zikhombisa umugqa we ukuhlangana phakathi kwendawo ebandayo nengaphambili efudumele. Imvamisa zihambisana nemvula enamandla.
