rainfall producer in the U.S. during the warm season, causing natural disasters and severe weather every year. Global climate models have large uncertainty in projecting precipitation changes in the future climate. Here we developed a simple Lagrangian parcel
model (includes single- and multi-column models) to investigate the impact of global warming on MCS initiation and growth. The single-column parcel model projects a mean precipitation decrease over the central U.S. and an increase to its east, in agreement
with the CMIP5 model projection. It also highlights the crucial role of current climate mean state model bias in influencing future mean precipitation projection. As for convective population, the model captures the decreased occurrence frequency of weak to
moderate convection and increased frequency of strong convection due to the increased CAPE and CIN, in agreement with convection-permitting regional simulations. The multi-column parcel model captures readily the cold pool-induced upscale growth feature. It
simulates smaller mesoscale clusters over the central U.S. under global warming due to gust front slowdown and subsidence strength enhancement. The model should be a useful tool for investigating the impact of global warming on MCS at mid-latitudes and providing
useful guidelines to improve GCM simulations.<span class="x_ContentPasted0" style="line-height:20.5042px; font-family:Arial,sans-serif; margin:0px; color:rgba(0,0,0,0.85)"></span></div>
