El kumanikidza gradient Inoshandiswa musainzi sefizikisi uye meteorology. Icho chiyero chekukurumidza kuchinja kudzvinyirira mune imwe nzira mumvura. Mvura iyi inogona kuva mweya, mvura kana zvimwewo. Izvo zvakakosha zvikuru mune meteorology kuziva mafambiro emhepo. Mukuwedzera, the pressure gradient mumhepo inogona kukanganisa mamiriro ekunze.
Naizvozvo, muchinyorwa chino tichatsanangura kuti chii chinonzi pressure gradient, hunhu hwayo uye nekubatsira kwayo zvese mumeteorology uye mufizikisi.
Chii chinonzi pressure gradient
pressure gradient zvinoreva kushanduka kwesimba sekushanda kwechinzvimbo mumvura. Mune mamwe mazwi, ndiyo chiyero chekukurumidza kuchinja kudzvinyirira mune imwe nzira mumvura.
The pressure gradient inogona kunzwisiswa zvirinani nekufunga mvura inenge yazorora. Kana chinhu chikaiswa mumvura, dzvinyiriro iri pasi pechinhu inenge yakura kudarika kudzvanywa kuri pamusoro. Izvi zvinodaro nekuti huremu hwechinhu hunoita simba rekudzika pamvura, zvichiwedzera kumanikidza kuzasi. The pressure gradient, munyaya iyi, yakanaka, kubvira kudzvinyirira kunowedzera paunenge uchidzika mumvura.
Iyo yekumanikidza gradient inogona zvakare kuve isina kunaka, zvinoreva kuti kudzvanywa kunoderera paunenge uchidzika mumvura. Semuenzaniso, kana mvura ichifamba, kudzvanywa kuri pamusoro pemvura kunenge kuri kushoma pane kudzvanywa kuri pasi. Izvi zvinodaro nekuti mvura inofamba inosangana nesimba rekukwesha pamusoro pepamusoro, izvo zvinodzikisira kumanikidza munzvimbo iyoyo. The pressure gradient panyaya iyi inenge isina kunaka.
Iyo yekumanikidza gradient yakakosha mune akawanda mafizikisi emvura, kusanganisira fluid dynamics uye sound wave theory. Kunyanya, kusiyanisa kwekumanikidza kwemvura mumvura kunogona kushandiswa kuona kumhanya kwemvura kana simba rinowanikwa nezvinhu zvakanyudzwa mairi.
Zvinoverengerwa sei
Pressure gradient inoverengerwa semwero wekuchinja kwekumanikidza maererano nekufamba kune imwe nzira mumvura. Kureva kuti, chiyero chekuchinja kwekumanikidza munzira yakatwasuka kana yakatwasuka inogona kuverengerwa, semuenzaniso.
Kuverenga kudzvanywa gradient munzira yakatwasuka, iyo equation inogona kushandiswa:
∆P/∆z
apo ∆P ndiwo musiyano wekumanikidzwa pakati pemapoinzi maviri munzira yakatwasuka uye ∆z ndiyo chinhambwe chakatwasuka pakati pemapoinzi maviri. Kana mhedzisiro iri yakanaka, zvinoreva kuti kudzvanywa kunowedzera paunenge uchidzika mumvura uye kudzvanywa kuri kuita zvakanaka. Kana mhedzisiro yacho isina kunaka, zvinoreva kuti kudzvanywa kunodzikira paunenge uchidzika mumvura uye kudzvanywa gradient kwakashata.
Kuverenga kudzvanywa gradient munzira yakachinjika, iyo equation inogona kushandiswa:
∆P/∆x
apo ∆P ndiyo mutsauko wekumanikidza pakati pemapoinzi maviri munzira yakachinjika uye ∆x ndiyo chinhambwe chakachinjika pakati pemapoinzi maviri. Kana chigumisiro chiri chakanaka, zvinoreva kuti kudzvinyirira kunowedzera munzira ye ∆x uye kudzvinyirira gradient kwakanaka. Kana mhedzisiro yacho isina kunaka, zvinoreva kuti kudzvinyirira kunoderera munzira ye ∆x uye iyo yekumanikidza gradient haina kunaka.
Inotarwa seyero yekuchinja kwekumanikidza maererano nekureba kune imwe nzira mumvura. Izvi zvinotibvumira kuti tinzwisise kusiyana kwekumanikidzwa mumvura uye simba rayo pamafambiro emvura uye zvinhu zvakanyura mairi.
pressure gradient mufizikisi
Pressure gradient chiyero chakakosha mumagetsi mechanics nekuti inogona kukanganisa kuyerera kwemvura uye simba rinoshanda pazvinhu zvakanyudzwa mumvura. Somuenzaniso, the kumanikidza gradient Izvo zvakakosha mukufambiswa kwemvura, sezvo kuyerera kwemvura kuchigona kunzwisiswa setsika yemvura inofamba ichibva munzvimbo ine dzvinyiriro huru ichienda kunzvimbo ine simba shoma. Kukwirisa kukwidza gradient kune imwe nzira kunogona kuratidza kukurumidza kuyerera kwemvura munzira iyoyo.
Uyewo, iyo pressure gradient yakakoshawo pakunzwisisa kuramba kufamba kwezvinhu zvakanyudzwa mumvura. Kazhinji, kuramba kufamba kwechinhu kunokonzerwa nesimba rekukwesha rinoshanda pachinhu chasangana nemvura. Iyo pressure gradient inogona kukanganisa iri friction force, uye nekudaro, kuramba kufamba kwechinhu.
pressure gradient Izvo zvakakoshawo mudzidziso yemafungu enzwi, sezvo kumhanya kweruzha mumvura kunoenderana nekusiyana kwekumanikidza mumvura. Naizvozvo, iyo pressure gradient inoshandiswa kuverenga kumhanya kwemasaisai eruzha mumvura.
kukosha mune meteorology
Dzvinyiriro gradient yakakoshawo mune zvemamiriro ekunze sezvo kushanduka kwemhepo yemuchadenga uye kutsika kwemhepo mumhepo kuchikanganisa mamiriro ekunze uye mafambiro emhepo.
Muchidzidzo chemamiriro ekunze, pressure gradient inoshandiswa kuona kwainoenda nekumhanya kwemhepo. Kutungamira kwemhepo kunotsanangurwa senzira iyo mhepo iri kuyerera. kubva munzvimbo yekumanikidza yakakwira kuenda kunzvimbo ine yakaderera. Kumhanya kwemhepo kunotariswa nehukuru hwekudzvanyirira gradient, kuva mukuru kana mutsauko wekumanikidza pakati pemapoinzi maviri wakakura.
Pamusoro pezvo, kusimba kwesimba kwakakoshawo mukuumbwa kwemamiriro ekunze akadai semadutu nemadutu. Iye kumanikidza gradient Muchadenga, inogona kuburitsa mhepo dzinotenderera dzakatenderedza nzvimbo yakaderera-kudzvanywa, izvo zvinogona kutungamira mukuumbwa kwemadutu emumhepo uye madutu.
Iyo pressure gradient yakakoshawo mukugadzirwa kwemamiriro ekunze, idzo inzvimbo dzinowanikwa mhepo dzemhepo dzine tembiricha dzakasiyana, hunyoro uye kumanikidzwa. Mafaro anoumbwa kana mhepo inotonhora yasangana nemhepo inodziya, isina kusimba zvishoma, ichigadzira kusimba kunokonzeresa makore uye kunaya kwemvura kuumba.
The pressure gradient chiyero chakakosha mumeteorology, sezvo ichipesvedzera kwainoenda nekumhanya kwemhepo, kuumbwa kwemamiriro ekunze akadai semadutu nemadutu, uye kuumbwa kwemamiriro ekunze. Kunzwisisa uye kuyera kunyura kwemhepo mumhepo kwakakosha pakunzwisisa uye kufanotaura mamiriro ekunze nemafambiro emhepo.
Ndinovimba kuti neruzivo urwu unogona kudzidza zvakawanda nezve kudzvanywa gradient uye maitiro ayo.
