Short summary
Asian dust is one of the important components in modern and past climate change via its effects, including snow-darkening and direct radiation. We employed model experiments to evaluate these effects on Indian monsoon and found that the monsoon onset responds significantly to both. Snow-darkening effect weakens the monsoon, but direct radiative effect intensifies it. Besides the previous Tibetan Plateau studies proposed, our work highlights the importance of temperature change over dust sources.
