My main research interest is in advancing climate science by exploiting emerging atmospheric modeling algorithms of opportunity, including (1) turbulence- or cyclone-permitting variants of global cloud superparameterization that are just now becoming possible on next-gen (e.g. GPU-based) supercomputers, and (2) machine learning emulation of atmospheric physics for interpreting and accelerating the simulation of global climate system dynamics including the complexity of cloud physics.

Washington]</i>. Over the past five years a UCI/UW/Stoney Brook collaboration has paved the way for high-resolution (i.e., boundary layer eddy-permitting) global superparameterization (Parishani et al. 2017,18), but the scientific ramifications of this have only begun to be explored. I welcome a new senior (postdoc- or research-scientist level) group member interested in understanding what relaxing traditional assumptions about the role of boundary layer turbulence means for broader climate dynamics, including the transitions and teleconnections between forms of low cloud organization and especially the aerosol-cloud indirect effect. Having expertise in global atmospheric dynamics, or the modeling or observation of aerosol-cloud interaction could be helpful; likewise interest in testing prototype algorithms on next generation supercomputers.</div><div class="" style="caret-color: rgb(0, 0, 0); color: rgb(0, 0, 0); margin: 0px; font-stretch: normal; line-height: normal; font-family: "Helvetica Neue"; min-height: 14px;"><br class=""></div><div class="" style="caret-color: rgb(0, 0, 0); color: rgb(0, 0, 0); margin: 0px; font-stretch: normal; line-height: normal; font-family: "Helvetica Neue";"><b class="">2. Exploring tropical cyclone or diurnal cycle dynamics at an ambitious new limit of global superparameterization (or machine learning emulation of same) </b><i class="">[Funding: DOE, collaborative with a large team at LLNL, PNNL].</i> Funding for this position is through my role as one of two University Partners in the DOE’s Exascale Computing Project (ECP). It is an exciting time since the DOE-ECP has just succeeded in a 3-year mission to port the embedded cloud-resolving model (CRM) calculations used in superparameterization to graphical processor units, which are fueling a new step change in national supercomputing capacity. The reward is a newfound ability to run on the world’s best supercomputer (Summit, 200-petaflops), where previously unimaginable limits of cloud-resolving model resolution can now be explored. At UC Irvine I am looking for a scientist interested in engaging with this team of DOE researchers by helping analyze their first prototype model (i.e., the first 25-km exterior resolution superparameterized global model, with one million embedded CRMs), including its unfamiliar emergent diurnal cycle and hurricane dynamics. Applicants interested in machine learning for advancing climate prediction and dynamics are equally welcome: This model is generating a very data- and physics-rich library that could be helpful for training deep learning emulators to interpret geographic variations in convective system dynamics, or develop new data-driven convective parameterizations. The overall goal is to do such phenomenological and climate-change </div><div class="" style="caret-color: rgb(0, 0, 0); color: rgb(0, 0, 0); margin: 0px; font-stretch: normal; line-height: normal; font-family: "Helvetica Neue";">science, while also helping with the DOE team’s broader vision of making this prototype into an operationally-useful convection-permitting model.</div><div class="" style="caret-color: rgb(0, 0, 0); color: rgb(0, 0, 0); margin: 0px; font-stretch: normal; line-height: normal; font-family: "Helvetica Neue"; min-height: 14px;"><br class=""></div><div class="" style="caret-color: rgb(0, 0, 0); color: rgb(0, 0, 0); margin: 0px; font-stretch: normal; line-height: normal; font-family: "Helvetica Neue";"><b class="">3.

Beyond ECP, the DOE also has an ambitious plan to make a global cloud resolving model that runs effectively on GPUs, with a great and growing team including leadership from Peter Caldwell at LLNL. I am seeking someone interested in helping with this effort by exploring whether machine learning emulation of aerosol-cloud interaction calculations is a viable strategy for porting costly calculations to GPU, and as a dynamical systems summary tool of the associated physics. Candidates with existing domain expertise on aerosol nucleation physics or aerosol cloud interaction are especially encouraged. Our group has had some recent success in emulating non-aerosol aspect of climate model physics (e.g. Rasp et al. 2018; Beucler et al., 2019) so in-house training on the practicalities of a deep learning workflow is available within the group already.</div><div class="" style="caret-color: rgb(0, 0, 0); color: rgb(0, 0, 0); margin: 0px; font-stretch: normal; line-height: normal; font-family: "Helvetica Neue"; min-height: 15px;"><b class=""></b><br class=""></div><div class="" style="caret-color: rgb(0, 0, 0); color: rgb(0, 0, 0); margin: 0px; font-stretch: normal; line-height: normal; font-family: "Helvetica Neue";"><b class="">For all of these positions </b>I am flexible about logistics and job titles -- I am mostly hunting for talent and meaningful collaboration with fun, independent people.
