. ▁Because ▁power ▁available ▁in ▁wind ▁increases ▁as ▁the ▁cube ▁of ▁velocity ▁( the ▁velocity - c ub ed ▁law ), ▁assuming ▁other ▁parameters ▁remaining ▁the ▁same , ▁dou bling ▁a ▁wind ' s ▁velocity ▁gives ▁ 2 3 = 8 ▁times ▁the ▁power ; ▁tri pling ▁the ▁velocity ▁gives ▁ 3 3 = 2 7 ▁times ▁the ▁available ▁power . ▁With ▁stead ier ▁and ▁more ▁predict able ▁wind s , ▁high - alt itude ▁wind ▁has ▁an ▁advantage ▁over ▁wind ▁near ▁the ▁ground . ▁Being ▁able ▁to ▁locate ▁H A WP ▁to ▁effective ▁alt itudes ▁and ▁using ▁the ▁vertical ▁dimension ▁of ▁air space ▁for ▁wind ▁far ming ▁brings ▁further ▁advantage ▁using ▁high - alt itude ▁wind s ▁for ▁generating ▁energy . ▁ ▁High - alt itude ▁wind ▁gener ators ▁can ▁be ▁adjust ed ▁in ▁height ▁and ▁position ▁to ▁maxim ize ▁energy ▁return , ▁which ▁is ▁imp ract ical ▁with ▁fixed ▁tower - mount ed ▁wind ▁gener ators . ▁ ▁In ▁each ▁range ▁of ▁alt itudes ▁there ▁are ▁alt itude - specific ▁concerns ▁being ▁addressed ▁by ▁research ers ▁and ▁developers . ▁As ▁alt itude ▁increases , ▁t eth ers ▁increase ▁in ▁length , ▁the ▁temperature ▁of ▁the ▁air ▁changes , ▁and ▁ ▁vulner ability ▁to ▁atmos pher ic ▁light ning ▁changes . ▁With ▁increasing ▁alt itude , ▁expos ure ▁to ▁li abilities ▁increase , ▁costs ▁increase , ▁tur bul ence ▁expos ure ▁changes , ▁lik elihood ▁of ▁having ▁the ▁system ▁fly ▁in ▁more ▁than ▁one ▁direction al ▁str ata ▁of ▁wind s ▁increases
