太阳辐射修正(SRM)减少了二氧化碳引起的全球平均水循环的变化,而不成比例地减少了二氧化碳引起的平均表面温度的增加。因此,如果SRM被用来抵消所有二氧化碳引起的平均变暖,那么全球平均降水量将比未受干扰的气候下的降雨量要少。在这里,我们表明,二氧化碳和SRM的平均水文效应之间的不匹配可以通过光谱调节SRM干预措施(比其他波长更多地减少某些波长的日照)来部分缓解。通过将太阳调光集中在近红外波长,其中H2O具有强烈的吸收波段,可以抵消二氧化碳对对流层能量收支的直接影响,从而将对平均水文周期的扰动降至最低。辐射-对流平衡的理想化云解模拟证实,即使向大气中添加了大量二氧化碳,光谱调谐的SRM也可以同时将平均表面温度和降水量保持在其未受扰动的值。
Solar radiation modification (SRM) reduces the CO2‐induced change to the mean global hydrological cycle disproportionately more than it reduces the CO2‐induced increase in mean surface temperature. Thus, if SRM were used to offset all CO2‐induced mean warming, global‐mean precipitation would be less than in an unperturbed climate. Here, we show that the mismatch between the mean hydrological effects of CO2 and SRM may partly be alleviated by spectrally tuning the SRM intervention (reducing insolation at some wavelengths more than others). By concentrating solar dimming at near‐infrared wavelengths, where H2O has strong absorption bands, the direct effect of CO2 on the tropospheric energy budget can be offset, which minimizes perturbations to the mean hydrological cycle. Idealized cloud‐resolving simulations of radiative‐convective equilibrium confirm that spectrally tuned SRM can simultaneously maintain mean surface temperature and precipitation at their unperturbed values even as large quantities of CO2 are added to the atmosphere.
