Chombo chofufuzira chikuloweraENANyanja mwadzidzidzi inayamba kugwedezeka mwamphamvu, liwiro lake likutsika kuchoka pa mfundo 15 kufika pa mfundo zisanu, ngakhale kuti panyanja pali bata. Ogwira ntchitoyo adakumana ndi "wosewera wosawoneka" wodabwitsa kwambiri wam'nyanja: mafunde amkati.
Kodi mafunde amkati ndi chiyani? Choyamba, tiyeni timvetsetse “sangweji ya m’madzi a m’nyanja.”
Mafunde omwe timawawona ndi "mafunde apamtunda" akuzungulira pamwamba; Koma mafunde a m’kati mwa nyanjayo amabisika mkati mwa madzi a m’kati mwa nyanjayo. Ganizirani za madzi a m'nyanja akugawidwa kukhala "sangweji": gawo lapamwamba ndi lopepuka (kutentha kwapamwamba, kutsika kwa mchere), pamene m'munsi ndi wolemera (kutsika kutentha, mchere wambiri). Kuphatikizika pakati pa zigawo ziwirizi ndi kachulukidwe. Mafunde a m’nyanja akawombana ndi mapiri kapena zisumbu za pansi pa madzi, kapena mphepo ikagwedezeka pamwamba pa madziwo, kusefukira kwake kumakhala ngati chingwe choduka, kumatulutsa mafunde amkati amene amakwera ndi kutsika.
Kodi mafunde amkati ndi amphamvu bwanji? Mukukhudzidwa kwambiri ndi izi.
Musaganize kuti mafunde a m'kati mwathu sakuchititsa mantha chifukwa chakuti abisika mozama. Mphamvu zawo zimatha "kuwongolera" ntchito zapamadzi mosavuta:
✅ "Msampha Wosaoneka" wa Sitima zapamadzi: Panthawi ya Nkhondo Yachiwiri Yapadziko Lonse, sitima zapamadzi zomwe zidalowa m'malo ozungulira mkati zidaponyedwa kumtunda ndi mafunde amphamvu, ndikuwulula zomwe akufuna. Masiku ano, sitima zapamadzi zimayang'ana "zoneneratu za mafunde amkati" zisanayende kuti zipewe malo oopsa.
✅ “Kupereka Zakudya Zam’madzi” Kumalo Opherako Usodzi: Mafunde amkati akamakwera, amakoka zakudya (monga ma phosphates ndi nitrate) kuchokera pansi pa nyanja kupita kumtunda, zomwe zimapatsa thanzi plankton. Usodzi wambiri ku South China Sea m'dziko langa umadalira mafunde amkati kuti "adyetse" nsombazo!
✅ "Mayeso Osaoneka" a Umisiri Wam'madzi: Zingwe zapansi pamadzi ndi nsanja zobowola mafuta zitha kuonongeka ndi mafunde ngati akumana ndi mafunde amphamvu amkati. Mafuta a Gulf of Mexico atatayikira mu 2010, asayansi adawunika momwe mafunde amkati amakhudzira kufalikira kwa mafuta.
Kodi “mafunde amkati” angaonedwe bwanji?
M'mbuyomu, ogwira nawo ntchito adadalira "kumverera" kwa mafunde amkati, koma tsopano matekinoloje apamwamba akupezeka:
● Kuonera patali patali: Tikamaona mmene madzi a m’nyanja amasinthira komanso mmene amakwera, tingathe “kuzindikira” mafunde a m’kati mwake (mofanana ndi kupeza chinthu mwa mthunzi wake);
● Mabotolo apansi pamadzi: Zida zowunikira pansi pamadzi pafupi ndi thermocline kuti zilembe matalikidwe ndi liwiro la mafunde amkati mu nthawi yeniyeni;
● Maloboti apansi pa madzi: Ajambula zithunzi zosonyeza matanthauzo apamwamba a mafunde amkati omwe akuyendetsa madzi a m’nyanjamoENANyanja.
Frankstar imagwira ntchito poyang'anira mafunde a m'nyanja, kupangasensa akatswirindibuoy solutions.
Ndi chitukuko cha kuyang'anira zachilengedwe zam'madzi, uinjiniya wam'madzi, ndi mphamvu zam'nyanja zongowonjezwdwa, zida zolondola komanso zodalirika zopezera mafunde amphamvu zikukhala zofunikira kwambiri. Monga katswiri wokonza mafunde a mafunde ndi ma buoys, Frankstar akudzipereka kupanga zinthu zapamwamba, zosavuta kugwiritsira ntchito zomwe zingathe kugwirizanitsa ndi zovuta za m'nyanja, ndipo zimalimbikitsa mwakhama ntchito yawo mu kafukufuku wa sayansi, zomangamanga, mphamvu, ndi zina.
Pitani kwathuwebusayitikuti mudziwe zambiri zamalonda, maphunziro amilandu, ndi mapepala oyera aukadaulo.
