The response of coastal stratocumulus clouds to agricultural irrigation in California

摘要: Stratocumulus clouds (SC) often exist over the eastern subtropical oceans during summer and have significant impacts on surface radiation budget. Both atmospheric subsidence lower troposphere stability (LTS) been found to play important roles in maintaining SC. Using global climate model simulations, we find that irrigation California's Central Valley results a decrease of land temperature, leading smaller land-sea heat contrast, corresponding reduction sea breeze, subsidence, LTS near-coastal region. The directly drives modeled SC coverage, it would arguably do so reality because well-known link between coverage. Consequently, simulated absorbed solar this region increases by 8 W/m2 (3.7%) due cover, resulting warming at Earth's surface. This study has implications for how can change with regard future climate. In contrast general effects formation SC, our suggest practices may drive nearby
