Nguwuphi umahluko phakathi kwentsholongwane kunye nesitshingitshane?

I-anticyclone kunye nesiphepho

Umahluko phakathi kwe-anticyclone (A) kunye ne-squall (B)

Izaqhwithi kunye ne-anticyclones zibhekisa kuxinzelelo olwahlukileyo emoyeni. Uxinzelelo lomoya lulinganiswa ngee-millibars (mbar). I-millibar ilingana newaka le-1 bar, kwaye ibha ilingana ne-1 atmosphere (atm). Kubalulekile ukuba wazi ukuba lithetha ukuthini i-millibar, kuba umahluko weebhiliyoni ezininzi okanye ezingaphantsi kule ngingqi kudala uqhwithela kunye neentsholongwane.

Ngaphambi kokuya kwiinkcukacha, ii-anticyclone kunye neenkqwithela zichonga ngokulula kwimephu ethatha i-isobars. Ukuba kukho uxinzelelo olungaphezulu kwesiqhelo, umzekelo u-1024 mb, kuxa sithetha nge-anticyclone. Xa uxinzelelo luphantsi, umzekelo 996 millibars, njengoko kubonakala emfanekisweni, sithetha ngesiqhwithi. Ukusuka apha, imozulu ehambelana noxinzelelo olwahlukileyo yahlukile.

I-anticyclone

indawo ecacileyo yesibhakabhaka

Ngokwesiqhelo Singayithelekisa nexesha elizinzileyo, kunye nesibhakabhaka esicacileyo kunye neLanga. Uxinzelelo lwayo lumalunga ne-1016 millibars okanye nangaphezulu.

Umoya kwi-anticyclone uzinzile ngakumbi kunomoya ojikeleze wona. Emva koko, umoya wehla usiya emoyeni, uvelisa into eyaziwa ngokuba yi "subsidence." Ukuhlala ngolu hlobo kuthintela ukubakho kwemvula. Indlela umoya owehla ngayo iyahluka ngokuxhomekeke kubume belizwe apho sikhoyo. Kwintshona yekhweyitha, ijikeleza ezantsi kwicala ejonge kwewotshi. Kwaye kwi-hemisphere esemazantsi, ngokuchaseneyo.

Isaqhwithi

amafu emvula

Ngokuchasene ne-anticyclone, inxulumene nemozulu engazinzanga, isibhakabhaka sinamafu nemvula. Uxinzelelo lwayo lungaphantsi kwe-1016 millibars.

Isalathiso sokujikeleza komoya kwisaqhwithi, esithi kule meko sinyukele phezulu, sikwenze oko ngokuchaseneyo ne-anticyclone. Oko kukuthi, ngokwewotshi kwi-hemisphere esemazantsi kunye nokuhamba ngasekhohlo ukuya kwi-hemisphere esemantla.

Ngokwesiqhelo bazisa imimoya, kwaye banciphise ubushushu, Ehlotyeni nasebusika. Ihlala ivela ngenxa yokungena kwemitha embalwa yelanga, njengoko amafu ebonakalisa ukuyithintela ukuba ingadluli.
