Rangarira ndima iri pasi apa uye ipapo pindura mubvunzo gare gare mumutauro mumwe chetewo sechikamu:  Passage: Spherical harmonic analysis inogona kushandiswa kusiyanisa zvemukati kubva kune zvekunze kana zviyero zviripo pane zvinopfuura imwechete kukwirira (semuenzaniso, pasi pekucherechedza uye satellites). Pakadaro, izwi rimwe nerimwe rine coefficient gml kana hml rinogona kupatsanurwa kuva mazwi maviri: rimwe rinoderera neradius se1 / rl + 1 uye rimwe rinowedzera neradius se rl. Mashoko anowedzera anowirirana nemanyuko okunze (zvinoitika mu ionosphere uye magnetosphere). Zvisinei, avhareji pamusoro pemakore mashomanana mipiro yokunze avhareji kusvika zero. Mashoko akasara anofanotaura kuti mikana yechitubu chedipole (l=1) inodonha se1/r2. Munda wamagineti, uri chigadzirwa chemasimba, unodonha se1⁄r3. Quadrupole terms inodonha se1 / r4, uye higher order terms inodonha nokukurumidza zvikuru neradius. Nharaunda yenyaya yokunze inenge hafu yenharaunda yepasi. Kana munda uri pamuganhu wedenga nechepasi uchikodzera maharmoniki emuchadenga, chikamu chedipole chiri chiduku nechikamu che8 pamusoro, chikamu chequadrupole nechikamu che16, zvichingodaro. Nokudaro, zvinhu zvine urefu hwemasaisai makuru bedzi zvinogona kuonwa pamusoro. Kubva pamashoko akasiyana-siyana, zvinowanzofungidzirwa kuti mashoko anosvika padanho 14 chete kana kuti pasi ane mavambo awo munheyo. Aya ane urefu hwemafungu anenge makiromita 2.000 kana kuti pasi. Zvinhu zviduku zvinonzi zvinokonzerwa nokusaenzana kweganda renyika.  Mubvunzo: chii chinofungidzirwa kuva bedzi mashoko anogona kuva namavambo munheyo?
