ʻAʻole hiki iā mākou ke hana i nā lei aniani maʻamau wale nō, akā hoʻomohala ʻia ʻenehana uhi. ʻO ka lei aniani i uhi ʻia he huahana hou o nā lei aniani i hoʻomohala ʻia i nā makahiki i hala iho nei, i hoʻohana ʻia no ka pālahalaha ʻana o ka graticule alanui. Me nā charcteristics maikaʻi loa, ua nānā nui ka hapanui o nā mea hoʻohana iā ia.

Ua mālama ʻia ka lei aniani i uhi ʻia me nā meaola kiʻekiʻe ma luna o ko lākou ʻili, no laila ke lawe nei i nā hiʻohiʻona ʻoi aku ka maikaʻi. Ua hoʻomohala kā mākou ʻoihana i kēia huahana kūʻokoʻa ma hope o ke komo ʻana i ʻenehana holomua mai nā ʻāina ʻē a loaʻa iā ia nā hiʻohiʻona maikaʻi aʻe:
ʻAʻole maʻalahi ka holoi ʻia o nā peʻa aniani i ke kahili. I ke kaʻina o ka mālama ʻana a me ka hoʻohana ʻana, nā ʻāpana aniani i maʻalahi ka maʻa i ka lewa i kahi lewa, alakaʻi ia i ka lūlū ʻana o ka malamalama, a no laila e hoʻohuli i ke aniani pololei.

ʻO nā ʻāpana aniani i uhi ʻia i nā mea he ʻano mea kūlohelohe i ʻoi aku paha ka hōʻoluʻolu me nā mea uhi alanui. ʻOiai e pālahalaha ʻia ma ke ala graticule ʻaoʻao, ʻaʻole maʻalahi ia e hele mai, ʻoi aku ka ikaika o ka adhesion ikaika i hoʻohana pinepine ʻia ma ka uhi ʻana i nā mea graticule o ka temperrature mau (me ka hoʻopili ʻana o ka mea hiki ke hoʻoheheʻe ʻia ka wai) a mālama paha i nā hopena aniani māmā no kahi manawa lōʻihi.

ʻOi aku ka maikaʻi o ka hoʻopili ʻana o nā lei aniani me ka uhi ʻana o ke ala, hiki ke kāohi ʻia ka sedimentation o ka ʻāpana ma hope o ka heʻe ʻana o ka surfacer ma o nā pēpē liʻiliʻi gals i mea e hōʻoia ai i ka hopena o ka graticule

He wai maikaʻi maikaʻi nā peʻa aniani i uhi ʻia, me ke ʻano o ka pale ʻole ʻana. Ka hoʻolaha ʻana, maʻalahi ke kūkulu ʻana a me ka hopena noʻonoʻo maikaʻi. Hōʻoia ʻia ka hiki ke mālama ʻia ma kahi o 15% ka nui o ka hoʻohana.
