Zvinhu Zvinokonzera Mafashamo Uye Hukama Hwawo Nemamiriro Ekunze
Mafashamo ndeimwe yenjodzi dzinoitika kakawanda muIndonesia dzinoitika mumvura. Zviitiko izvi hazvingokonzere kurasikirwa nezvinhu chete asiwo zvinokanganisa hutano hwevanhu, dzidzo, kutakura, uye mabasa ehupfumi. Kuti tinzwisise mafashamo zvizere, tinofanira kuaona semhedzisiro yekudyidzana kwezvinhu zvakasiyana-siyana: mamiriro ekunze nemamiriro ekunze (meteorology), hunhu hwenzvimbo (topography uye manejimendi yemvura), uye mabasa evanhu (kuchinja kwekushandiswa kwenyika uye manejimendi yemvura). Meteorology inoita basa rakakosha nekuti ndiyo "chinokonzera" mafashamo kuburikidza nemvura, maitiro emhepo, uye mamiriro ekunze anokanganisa kusimba uye nguva yekunaya kwemvura.
1. Mafashamo sechiitiko chemvura
Izwi rekuti "hydrometeorology" rinobatanidza zvinhu zviviri: mvura (mvura) uye mamiriro ekunze (mamiriro ekunze). Mafashamo anowanzoitika kana huwandu hwemvura huchipinda munzvimbo—kungave kubva mumvura yemunzvimbo kana kubva mukuyerera kwerwizi—huchipfuura kugona kwenharaunda kuinyudza nekuidururira. Izvi zvinoreva kuti mafashamo haangokonzereswi nemvura chete, asi nekuda kwekusaenzana pakati pemvura inopinzwa uye kugona kwemaitiro echisikigo neekugadzira (madhiraini, nzizi, madhamu) ekugamuchira kana kuburitsa mvura iyoyo.
Munyaya iyi, mamiriro ekunze anoita basa sechikonzero. Zvisinei, huwandu hwemafashamo hunokonzerwa nezvimwe zvinhu zvakaita semamiriro emvura, shanduko mukushandiswa kwevhu, uye kushaya simba kwekugara.
2. Mvura inonaya : chinhu chinonyanya kunanga mamiriro ekunze
Chinhu chikuru chinokonzera mafashamo imvura yakawanda inonaya—ingava yakanyanya munguva pfupi (mvura yakawandisa) kana mvura inogara kwenguva refu (mvura inoramba ichinaya). Mhando mbiri idzi dzemvura dzine mhedzisiro dzakasiyana:
1. Mvura ine simba guru (yakawanda uye pfupi)
Izvi zvinowanzokonzera mafashamo anokurumidza kana mafashamo anokurumidza kuitika mumaguta. Mvura inonaya nekukurumidza zvekuti masisitimu emvura haakwanise kuibata, kunyanya kana madhireni akavharika kana kuti asina simba rakawanda.
2. Mvura inonaya kwenguva refu (maawa kusvika kumazuva)
Izvi zvinokonzera kuti ivhu rive rakazara, zvichiita kuti mvura ibude murwizi iwedzere zvishoma nezvishoma, yozozara. Izvi zvinowanzoitika munzvimbo huru dzemvura, kunyanya kana mvura ichinaya zvakaenzana kubva kumusoro kusvika pasi.
Mukuongorora mamiriro ekunze, kuwanda kwemvura uye nguva yemvura zvinokanganiswa nemamiriro ekunze akadai sehuwandu hwemvura, tembiricha, kumanikidzwa kwemhepo , uye mapatani emhepo. Kana mhepo yakazara nemhepo uye paine nzira yekusimudza mhepo (convection kana kusangana kwemhepo), mvura yakawanda inogona kudonha.
3. Zviitiko zvemamiriro ekunze zvinosimbisa kunaya kwemvura kwakanyanya
MuIndonesia, mamiriro ekunze akasiyana-siyana anogona kuwedzera mukana wemvura zhinji:
a. Mvura inonaya (mwaka wemhepo)
Indonesia inopesvedzerwa nehurongwa hwemvura inonaya pakati peAsia neAustralia. Munguva yemvura inonaya kumadokero (kunenge muna Mbudzi-Kurume), mhepo inounza mhepo ine hunyoro kubva kuIndian Ocean neSouth China Sea, zvichiwedzera mukana wekunaya kwemvura yakawanda. Matunhu mazhinji anowana mvura yakawanda. mwaka wemvura munguva iyi, saka njodzi yekufashamira kwemvura inowedzera, kunyanya kana mvura ikanaya nguva nenguva.
b. La Niña neEl Niño
ENSO Phenomenon (El Niño–Southern Oscillation) kukanganisa maitiro ekunaya kwemvura muIndonesia:
– La Niña inowanzo wedzera mvura inonaya munzvimbo dzakawanda dzeIndonesia. Mhepo inonyorova uye makore emvura anoumbwa zvakanyanya, zvichiwedzera njodzi yemafashamo.
– El Niño inowanzo kuderedza mvura uye inowedzera njodzi yekusanaya kwemvura, asi munguva yekuchinja kwemamiriro ekunze mvura yakanyanya inogona kuenderera mberi.
c. Madden–Julian Oscillation (MJO)
MJO ifungu remhepo rinotenderera kubva kumadokero kuenda kumabvazuva munzvimbo dzinopisa. Kana chikamu cheMJO chikapfuura pamusoro peIndonesia, kuumbwa kwemakore emvura kunowedzera, zvichiwedzera zvakanyanya mukana wekunaya kwemvura yakawanda nemafashamo.
d. Mamwe mafungu emhepo uye kusangana kwemhepo
Zvinhu zvakaita semafungu eRossby equatorial, mafungu eKelvin, kana nzvimbo dzinosangana nemhepo (wind convergence) zvinogona kukonzera kukura kwemakore ecumulonimbus, ayo anounza mvura yakawanda. Munharaunda, mhepo dzegungwa nemhepo yepanyika zvinogonawo kukonzera kuungana kwemvura masikati nemanheru, zvichikonzera mafashamo mumaguta.
e. Madutu emuchadenga (simba risingatariswe)
Indonesia haiwanzo kanganiswa zvakananga nemadutu emunzvimbo dzinopisa nekuda kwekuva pedyo kwayo ne equator, asi migumisiro yawo isina kunanga inogona kunge yakakosha. Madutu ari kumaodzanyemba kweIndonesia kana pamusoro peIndian Ocean anogona kukwezva mhepo ine hunyoro, zvichiita kuti mhepo iwedzere uye mvura inaye munzvimbo dzakati wandei, uye kuwedzera mafungu makuru anogona kuwedzera mafashamo emumahombekombe.
4. Mamiriro ekunze: sei mvura imwe chete ichigona kukonzera mafashamo akasiyana?
Meteorology inotsanangura "kuti mvura yakawanda sei inodonha kubva kudenga," ukuwo mamiriro epamusoro achitsanangura "zvinoitika kana mvura yasvika pasi." Nzvimbo mbiri dzine mvura imwe chete dzinogona kuva nemigumisiro yakasiyana nekuda kwezvinhu zvinotevera:
a. Nzvimbo uye geomorphology
Nzvimbo dziri pasi, madhamu, kana nzvimbo dziri pedyo nerwizi dzinogona kufashamirwa nemafashamo nekuti mvura inoyerera zvishoma nezvishoma. Kusiyana neizvi, nzvimbo dzine makomo dzinogona kusangana nemafashamo akangoerekana aitika kana mvura inoyerera nekukurumidza ikatakura marara nemarara.
b. Kugona kwerwizi uye mamiriro enzvimbo dzemvura
Nzizi dzine mukana wakakwana wekugamuchira mvura. Kana mvura ikanaya zvakanyanya kumusoro kwerwizi, mvura inoyerera inowedzera uye inogona kuzara pasi perwizi. Kukuvadzwa kwemiti iri kumusoro kwerwizi, kukurwa kwevhu, uye kudonha kwevhu kunogona kukonzera nzizi dzisina kudzika, zvichideredza kugona kwadzo uye zvichiwedzera njodzi yekufashamira kwemvura.
c. Mamiriro evhu uye huwandu hwevhu rakaguta
Ivhu rakatozara nemvura yakambonaya harikwanise kunwa mvura yakawanda. Ndosaka mafashamo achiwanzoitika mushure memazuva akati wandei emvura yakatevedzana, kunyangwe mvura yekupedzisira isingawanzova yakanyanya.
5. Zvinhu zvinokonzerwa nevanhu: kuwedzera njodzi yemafashamo anokonzerwa nemamiriro ekunze
Mafashamo anowanzova njodzi huru kwete nekuda kwemamiriro ekunze chete, asi nekuda kwekuwedzera kwekusagadzikana kunokonzerwa nemabasa evanhu:
a. Kukura kwemaguta nenzvimbo dzisingapindi mvura
Maguta ari kukura nekuwedzera kwekushandiswa kwekongiri, tarafa, uye zvivakwa zvisingapindi mvura. Nekuda kweizvozvo, kupinda kwemvura mumaguta kushoma uye mvura inoyerera pamusoro pemvura inowedzera. Mvura yainaya kare "yakachengeteka" inogona kuita mafashamo sezvo mvura ichiyerera zvakananga mumigwagwa nemumadhireni.
b. Kusakwana uye kuvharika kwemvura
Nzira dzakamanikana, dzisina kudzika, dzisina kuchengetwa zvakanaka, kana kuti dzisina marara dzinovhara kufamba kwemvura. Panyaya dzemamiriro ekunze, mvura yakawanda inogona kunaya, asi kana mvura isina kuyerera yakakwana, mafashamo anogona kuitika kunyangwe mvura isingagari kwenguva refu.
c. Kuchinja ivhu nekutema miti
Kuchera masango nenzvimbo dzine mvura dziri pedyo nerwizi kunoderedza kugona kwenzvimbo iyi kuchengetedza mvura. Mvura inonaya inokurumidza kupinda mumvura iri pamusoro pemvura, zvichiita kuti mvura ibude murwizi rwacho kakawanda uye mukana wekuti pave nemafashamo.
d. Kudonha kwevhu nemafashamo emvura
Munzvimbo dziri kumahombekombe, mafashamo anogona kukonzerwa nekusanganiswa kwemvura inonaya uye mafungu akakwira. Kuderera kwevhu nekuda kwekutorwa kwemvura yepasi pevhu uye huremu hwezvivakwa kunoderedza nzvimbo iyi, zvichiita kuti ive nyore kubatwa nemafashamo. Zviitiko zvemamiriro ekunze zvakaita semhepo ine simba uye kumanikidzwa kwakaderera zvinogonawo kukwidza huwandu hwegungwa kwenguva pfupi (madutu), zvichiwedzera mafungu akakwira.
6. Hukama huripo pakati pemamiriro ekunze neyambiro yekukurumidza kwemafashamo
Nekuti mamiriro ekunze anokanganisa mvura, kutarisa mamiriro ekunze kwakakosha pakuderedza njodzi yemafashamo. Zvimwe zvinoshandiswa zvakanyanya zvinosanganisira:
- Radar yemamiriro ekunze yekuona makore emvura uye simba remvura munguva chaiyo.
- Masatellite emamiriro ekunze ekutarisa kukura kwemakore uye kupararira kwemhute yemvura.
- Muenzaniso wekufanotaura mamiriro ekunze unoratidza mukana wemvura mumazuva mashoma anotevera.
- Kuongorora mamiriro ekunze emwaka kuti ufungidzire mukana wemwaka wemvura inonaya (semuenzaniso munguva yeLa Niña).
Zvisinei, yambiro yekukurumidza yemafashamo inoshanda inoda kubatanidzwa kwezvemamiriro ekunze uye zvemvura. Kufanotaura kwemvura kunofanirwa kushandurwa kuita fungidziro yekuwedzera kwekubuda kwemvura murwizi, mafashamo, kana mafashamo anogona kuitika. Nemamwe mashoko, chinodiwa hachisi "fungidziro yemvura chete," asi "fungidziro yemigumisiro."
7. Kesimpulan
Mafashamo anokonzerwa nekudyidzana kwakaoma pakati pezvinhu zvemamiriro ekunze nemamiriro ekunze. Mamiriro ekunze anoita basa guru kuburikidza nekunaya kwemvura kwakanyanya, maitiro emvura inonaya, uye zviitiko zvemumhepo pasi rose zvakaita seLa Niña neMJO. Zvisinei, kukanganisa kwemafashamo kunoenderana nemamiriro ekunze: kugona kwerwizi, mamiriro ekunze, kuwanda kwevhu, uye hunhu hwehutongi hwedunhu. Mabasa evanhu—kukura kwemaguta, kuparadzwa kwemiti, kuyerera kwemvura zvisina kunaka, uye kudzikira kwevhu—kazhinji zvinowedzera njodzi, zvichiita kuti mvura inaye ive njodzi.
Nekunzwisisa hukama huripo pakati pemafashamo nemamiriro ekunze, matanho akakodzera ekuderedza matambudziko anogona kuitwa: kusimbisa masisitimu ekunyevera emamiriro ekunze ekutanga, kuvandudza kurongeka kwemvura inoyerera uye nzvimbo, kuchengetedza nzvimbo dzinowana mvura, uye kuchengetedza nzvimbo dzinochengeterwa mvura nenzira inochengetedza nharaunda. Pakupedzisira, mafashamo haasi e "mamiriro ekunze akaipa" chete, asiwo ekugadzirira kwevanhu nenharaunda kugadzirisa mvura inouya.
Kana muchida, ndinogona kugadzirisa chinyorwa ichi kuita mazwi chiuru (parizvino chave pedyo), kana kuchichinja kuita shanduro yevadzidzi vechikoro chesekondari/vekoreji nemienzaniso yezviitiko zvemafashamo mumaguta akati wandei muIndonesia.
