Iyo periodic inosimuka uye inodonha yekuraira inotakurwa mafungu. Zvinoitika anenge maawa makumi maviri nemana oga oga. Zvinokonzerwa nekukweva kwemwedzi nezuva pamakungwa ePasi. Simba rinokweva reZuva, kunyange zvazvo rakakura kudarika reMwedzi, rine simba diki pamafungu nekuda kwechinhambwe charo kubva paNyika. Kuva pedyo kweMwedzi neNyika, kune rumwe rutivi, kune zvakanyanya kukosha pamafungu. Naizvozvo, masaisai nemwedzi zvine hukama hwakakosha.
Muchikamu chino tichakuudza zvose zvaunoda kuziva pamusoro pemafungu nemwedzi uye kuti zvinokanganisa sei gungwa.
Mafungu nemwedzi
Sezvo Nyika inotenderera, simba rinokweva rinokweva mvura kudivi rakatarisana neMwedzi, zvichiita kuti pave nemafungu makuru. Panguva imwecheteyo, mvura iri mhiri kweNyika inotsvairwawo, zvichikonzera rimwe fungu guru. Apo mvura inoserera, kuderera kwemvura kunoitika.
Mafungu emvura anogara achichinja-chinja muchikamu chegungwa, zvichikonzerwa nekukweva kweZuva neMwedzi maererano nePasi. Chokwadi ichi chinokonzeresa kutama kwemvura zhinji paPasi, sezvo zvichifurirwa nemitumbi yedenga iri pedyo nesu. Kukweva kweMwedzi kunokwana kuita 2-3 kusimba kudarika kweZuva, sezvo Mwedzi uri padyo nePasi.
Kuumbwa kwemafungu kunoitika mukati-kati memakungwa, zvichiita kuti simba rawo ripararire kunze uye richikanganisa mhenderekedzo dzegungwa pasi rose, zvichikonzera kudzikama nekuyerera kwegungwa. Makungwa ane mvura zhinji inofamba ichikonzerwa negiravhiti.
Mafambiro emvura akananga kumahombekombe kunozivikanwa nekuti “kuyerera”, ukuwo mvura ichidzokera kugungwa nokuda kwekukweva kweZuva uye zvikuru Mwedzi unonzi “ebb”. Kutenderera kwemvura uku kunogadzira ayo atinoti mafungu, kunova kuenderera nekuuya kwemvura pamahombekombe. Kutenderera uku kunogadzira mafungu maviri akakwirira uye maviri akadzikira zuva rega rega, zvichikonzera kuyerera kuviri kwemvura kumahombekombe uye maviri ebbs emvura akananga kugungwa. Pakupedzisira, kupera uye kuyerera kwemvura ndiyo inonyanya kufambisa simba shure kwemafungu.
Newton, mafungu uye mwedzi
Zvakaitwa naIsaac Newton kusayenzi zvinozivikanwa zvikuru, nebasa rake pamusoro pesimba rinokwevera zvinhu pasi uye sainzi yomugungwa richinyanya kufarirwa. Dzidziso dzaNewton dzesimba rinokwevera zvinhu pasi hadzina kungoumba hwaro hwefizikisi yemazuva ano, asi dzakatibatsirawo kunzwisisa magadzirirwo echadenga nekufamba kwechadenga. Zvidzidzo zvake musainzi yemvura, iyo yakaongorora kusangana kwakaoma pakati peMwedzi nemakungwa ePasi, zvakatungamira kune miono mitsva yemaitiro emafungu uye maitiro awo. Basa raNewton rinoramba riri chikamu chakakosha cheruzivo rwesainzi kusvika nhasi.
Tsananguro yemafungu acho iri munheyo dzakatangwa nemitemo yaNewton. Mutemo wekukweva kukwezvana pakati peNyika, Zuva neMwedzi unonyanya kuenderana nesimba regiravhiti. Newton akafungidzira kuti kukwezvana kuri pakati pezvinhu zviviri kunoenzana nehuremu hwazvo uye nekupesana nehupamhi hwechinhambwe chiri pakati pazvo.
Kuzvitaura neimwe nzira, kukweva kwegiravhiti pakati pezvinhu zviviri kusimba kana mhomho yazvo yakakura uye kana zvava pedyo. Nzira yeMwedzi yakatenderedza Nyika ine elliptical, sezvakangoitawo kutenderera kwedu kuZuva kuine denderedzwa. Kana uri Mwedzi, divi reNyika rakatarisana nawo rinowana simba regiravhiti rakasimba nekuda kwekuswedera kwaro kune satellite.
Izvi zvinoita kuti mvura yakawanda ikweverwe kwairi, zvichikonzera mafungu makuru. Kusiyana neizvi, divi rakapesana rinowana simba regiravhiti risina simba nekuda kwesimba repakati rePasi rinoenderana neMwedzi, zvichikonzera kudzikira kwemvura zhinji.
Pakushandisa formula yaNewton, zvakakosha kuziva kuti chinhambwe chinoita basa guru pane kuwanda pakuverenga simba rinokwevera zvinhu pakati pemiviri miviri. Nekuda kweizvozvo, simba rinokwezva rinoitwa neMwedzi rakakura zvakapetwa ka2 kusvika ku3 pane reZuva, zvisinei nehukuru hwekupedzisira. Nekuda kweizvozvo, masaisai emwedzi anoratidza huwandu hwakakura hwesimba zvichienzaniswa nemasaisai ezuva.
High tide uye kuderera kwemvura
Chiitiko chemvura yakakwira uye yakaderera chiitiko chemusikirwo chinoitika nekuda kwekukwezva kwemwedzi uye zuva pamakungwa ePasi. Munguva yemvura yakakwira, mwero wemvura uri pakakwirira payo, nepo panguva yemvura yakaderera, iri padanho rayo rakaderera. Iyi muenzaniso Inotenderera uye inoitika kaviri pazuva, nemaawa anenge matanhatu pakati pemvura yakakwira uye yakaderera. Chinhu chakakosha chezvipenyu zvemumhenderekedzo yegungwa uye chinoita basa rakakosha mukudzora zvipenyu zvemugungwa nekukukurwa kwemahombekombe.
Nzvimbo yepamusoro inosvika gungwa inozivikanwa semvura zhinji. Izvi zvinoitika kaviri pazuva, paine nguva yemaawa gumi nemaviri nemaminetsi makumi maviri nemashanu pakati pekuonekwa kwega kwega. Low tide, kana kuti nzvimbo yakadzikira panosvika gungwa, inoitikawo kaviri pazuva, nenguva imwe cheteyo semafungu emvura. Nguva yenguva yehafu-tide, inova nguva yakareba pakati pemvura zhinji uye yakaderera, Inguva 6 maawa, 12 maminitsi uye 30 masekondi. Nekuda kweizvozvo, mafungu anochinja zuva rega rega kwemaminitsi makumi mashanu.
Zvikoro zveSurf zvakavakirwa pa nzvimbo yereferenzi iyo inotora anenge 45-50 maminetsi kuseta nguva dzako dzezuva rinotevera rezuva rinotevera.. Iyi nzira inoshandiswa nekuti bhichi rega rega rine nzvimbo yakanaka yekusevha. Vanhu vakasiyana-siyana vanofanira kuziva kana mafungu makuru akaitika uye kana "ebb" yemvura inotanga, sezvo simba regungwa rinogona kuvakwevera mumvura yakadzika. Nokudaro, zvinokurudzirwa kunyura panguva yemvura yakaderera. Saizvozvowo, kuderera kwemvura ndiyo nguva yakafanira yevazhinji vanobata hove kuti vaende kunobata hove, kunyanya munguva dzemvura dzechirimo.
Ndinovimba kuti neruzivo urwu unogona kudzidza zvakawanda nezvemafungu nemwedzi.
