However, most previous studies have focused on the HC changes in response to the increasing CO2 forcing. We investigate the HC changes in response to the transient reversibility of the CO2 forcing by conducting a climate model experiment where CO2 concentration is systematically increased and then decreased in time. It is found that a poleward-shifted HC edge in a warm climate returns equatorward as CO2 concentration decreases, and the rate significantly differs between the two hemispheres. While the southern HC edge monotonically changes with CO2 concentration, the northern HC edge exhibits a super recovery, located on the equatorward side of the present-climate HC edge when CO2 concentration returns to the present level. Such a super recovery is associated with the hysteresis of the North Atlantic sea surface temperature. Our findings suggest that the HC edge change may result in the super recovery of subtropical dryness in the northern hemisphere.์ „์ง€๊ตฌ ์ˆ˜๋ฌธ ์ˆ˜์ง€๋ฅผ ๊ฒฐ์ •ํ•˜๋Š” ์ค‘์š”ํ•œ ์—ญํ• ์„ ํ•˜๋Š” ํ•ด๋“ค๋ฆฌ์…€ ๊ฒฝ๊ณ„๋Š” ์ง€๊ตฌ์˜จ๋‚œํ™”์— ๋”ฐ๋ผ ๊ทน๋ฐฉํ–ฅ์œผ๋กœ ํ™•์žฅํ•˜๋Š” ๊ฒƒ์œผ๋กœ ์•Œ๋ ค์ ธ ์žˆ๋‹ค. ๊ธฐํ›„ ๋ชจํ˜•์„ ์ด์šฉํ•œ ์„ ํ–‰์—ฐ๊ตฌ์—์„œ๋Š” ์ด์‚ฐํ™”ํƒ„์†Œ ์ฆ๊ฐ€์— ๋”ฐ๋ฅธ ํ•ด๋“ค๋ฆฌ์…€ ์—ฐ๊ตฌ์— ์ง‘์ค‘๋˜์–ด ์™”๋‹ค. ๋ณธ ์—ฐ๊ตฌ์—์„œ๋Š” ์ด์‚ฐํ™”ํƒ„์†Œ ์ฆ๊ฐ€ ๋ฐ ๊ฐ์†Œ์— ๋”ฐ๋ฅธ ๋‚จ๋ถ๋ฐ˜๊ตฌ ํ•ด๋“ค๋ฆฌ์…€ ๊ฒฝ๊ณ„์˜ ๋ณ€ํ™”๋ฅผ ์‚ดํŽด๋ณด์•˜๋‹ค. ์ด๋ฅผ ์œ„ํ•ด CESM1.2 ๋ชจํ˜•์„ ์ด์šฉํ•˜์—ฌ ์ด์‚ฐํ™”ํƒ„์†Œ ๋†๋„๋ฅผ 2000๋…„๋Œ€ ์ˆ˜์ค€(367 ppm)์—์„œ ๋งค๋…„ 1%์”ฉ ์ฆ๊ฐ€์‹œํ‚จ ํ›„ ๊ฐ™์€ ๋น„์œจ๋กœ ๊ฐ์†Œ์‹œํ‚จ ์‹œ๋‚˜๋ฆฌ์˜ค๋ฅผ ๋ถ„์„ํ•˜์˜€๋‹ค. ์ด์‚ฐํ™”ํƒ„์†Œ ๋†๋„ ์ฆ๊ฐ€์— ๋”ฐ๋ผ ๋‚จ๋ถ๋ฐ˜๊ตฌ ํ•ด๋“ค๋ฆฌ์…€ ๊ฒฝ๊ณ„๋Š” ๋ชจ๋‘ ๊ทน๋ฐฉํ–ฅ์œผ๋กœ ์ด๋™ํ•˜๋Š” ์–‘์ƒ์„ ๋ณด์˜€์œผ๋‚˜, ์ด์‚ฐํ™”ํƒ„์†Œ ๋†๋„ ๊ฐ์†Œ์— ๋Œ€ํ•ด ๋‚จ๋ฐ˜๊ตฌ ํ•ด๋“ค๋ฆฌ์…€ ๊ฒฝ๊ณ„๋Š” ๋Š๋ฆฌ๊ฒŒ ๋ฐ˜์‘ํ•˜๊ณ  ๋ถ๋ฐ˜๊ตฌ ํ•ด๋“ค๋ฆฌ์…€ ๊ฒฝ๊ณ„๋Š” ๋น ๋ฅด๊ฒŒ ๋ฐ˜์‘ํ•˜๋Š” ํŠน์ง•์„ ๋ณด์˜€๋‹ค. ๊ทธ ๊ฒฐ๊ณผ ์ด์‚ฐํ™”ํƒ„์†Œ ๋†๋„๊ฐ€ ์›๋ž˜ ์ˆ˜์ค€์œผ๋กœ ๋Œ์•„์™”์„ ๋•Œ ํ•ด๋“ค๋ฆฌ์…€์˜ ๊ฒฝ๊ณ„๋Š” ๋‚จ๋ฐ˜๊ตฌ๋Š” ์›๋ž˜ ์œ„์น˜๋กœ ๋Œ์•„์˜ค์ง€ ๋ชปํ•ด ๊ทน๋ฐฉํ–ฅ์— ๋จธ๋ฌด๋ฅธ ๋ฐ˜๋ฉด, ๋ถ๋ฐ˜๊ตฌ๋Š” ์›๋ž˜ ์œ„์น˜๋ฅผ ์ง€๋‚˜ ์ ๋„ ๋ฐฉํ–ฅ์— ์œ„์น˜ํ•˜์˜€๋‹ค. ๋‚จ๋ถ๋ฐ˜๊ตฌ ํ•ด๋“ค๋ฆฌ์…€ ๊ฒฝ๊ณ„์˜ ๋น„๋Œ€์นญ์ ์ธ ๋ฐ˜์‘์€ ์ด์‚ฐํ™”ํƒ„์†Œ ๊ฐ์†Œ ์‹œ๊ธฐ์— ๋‚˜ํƒ€๋‚œ ๋ถ๋ฐ˜๊ตฌ ์ค‘์œ„๋„ ๋Œ€๋ฅ˜๊ถŒ ์—ฐ์ง ๋ฐ”๋žŒ์‹œ์–ด์˜ ๊ธ‰๊ฒฉํ•œ ๋ณ€ํ™”์—์„œ ๋น„๋กฏ๋œ ๊ฒƒ์œผ๋กœ ํ™•์ธ๋˜์—ˆ๋‹ค. ์ด๋Š” ์ด์‚ฐํ™”ํƒ„์†Œ ์ฆ๊ฐ์— ๋”ฐ๋ฅธ ํ•ด์ˆ˜๋ฉด ์˜จ๋„์˜ ๋ฐ˜์‘ ์†๋„์˜ ์ฐจ์ด์™€ ๊ด€๋ จ ์žˆ๋Š” ๊ฒƒ์œผ๋กœ ๋‚˜ํƒ€๋‚ฌ๋‹ค. ๋น„๋กฏ๋œ ๋ถ๋ฐ˜๊ตฌ ์ค‘์œ„๋„ ๋Œ€๋ฅ˜๊ถŒ ์—ฐ์ง ๋ฐ”๋žŒ ์‹œ์–ด์˜ ๊ธ‰๊ฒฉํ•œ ๋ณ€ํ™”์—์„œ ์—ฐ๊ด€๋œ ๊ฒƒ์œผ๋กœ ํ™•์ธ๋˜์—ˆ๋‹ค. ์ด๋Ÿฌํ•œ ๋‚จ๋ถ๋ฐ˜๊ตฌ ํ•ด๋“ค๋ฆฌ์…€ ๊ฒฝ๊ณ„์˜ ๋ณ€ํ™”๋Š” ์•„์—ด๋Œ€ ์ง€์—ญ์˜ ๊ฑด์กฐ ๊ธฐํ›„์˜ ๊ฐ€์—ญ์„ฑ์—๋„ ์˜ํ–ฅ์„ ๋ฏธ์น  ์ˆ˜ ์žˆ์Œ์„ ์‹œ์‚ฌํ•œ๋‹ค.1.
