<div>TITLE: <i style="caret-color: rgb(0, 0, 0); color: rgb(0, 0, 0);">Seeing the forest for the trees: How spatial patterns in land–aerosol–atmosphere interactions shape cloud responses</i></div>
<div><br>
</div>
<div>ABSTRACT: Human activities impact clouds in many ways, notably through changes in land surface properties and aerosol emissions. Improving our understanding of land–aerosol–atmosphere interactions is essential for accurately assessing how clouds may change
in the future. This talk will focus on how the mesoscale (O(100km)) pattern of aerosol and surface perturbations—though often unresolved in large-scale models—can shape overall responses in clouds and rainfall.</div>
<div><br>
</div>
<div>First, I will demonstrate how spatial gradients in aerosol emissions, such as those around wildfires or urban areas, drive aerosol breeze circulations. These localized circulations can substantially alter the magnitude and spatial distribution of clouds
and rain.</div>
<div><br>
</div>
<div>Second, I will use high-resolution simulations and object-tracking methods to explore cloud responses to realistic patterns of tropical deforestation. Localized deforestation-driven changes to boundary layer processes drive mesoscale flow adjustments,
resulting in widespread reductions in shallow cloud cover, but increases in cloudiness along the boundary between forested and deforested areas. </div>
<div><br>
</div>
<div>Finally, I will present long-term satellite estimates of cloud responses to deforestation. Although deforestation impacts on cloudiness are robust, the magnitude of the cloud response is not uniform everywhere. Due to the background moisture and aerosol
environment, some areas are especially susceptible to deforestation-induced changes in cloud properties.</div>
<div><br>
</div>
<div>Understanding land–aerosol–atmosphere interactions in the context of their spatial patterns leads to a fuller picture not only of how land and aerosol perturbations impact clouds, but also where and when such perturbations might be most important for weather
and climate. </div>

<div>We look forward to seeing you there!</div>
