3 PhD positions at University of Hamburg
University of Hamburg/MPIM/CliCCS
Three PhD candidates will work on the following aspects of tropical circulation:
PhD1: diabatic processes in the upper troposphere
PhD1 will study the factors influencing upper tropospheric humidity and high-level clouds in the tropics with the goal to better understand high-cloud feedbacks on climate. The candidate will test emerging ideas concerning the role of radiation in the middle and upper troposphere, exploring the role of water vapor variability, ice clouds and mid-level convection. He/she will be using idealized and realistic numerical simulations and deploy insights from modelling to pose process related questions to satellite observations.
PhD2: spatial organization of precipitation in shallow convection
PhD2 will study controls of spatial organization of precipitation in shallow convection. He/she will analyze the role of variability of updrafts and cloud top heights to deposit moisture aloft and to initiate precipitation. The candidate will explore machine learning approaches to detect structures of clouds and precipitation from limited samples such as airborne measurements and will be involved in the EUREC4A campaign.
PhD3: propagation of organized tropical convection
PhD3 will apply the balanced/unbalanced decomposition of global circulation to study the role of large-scale Rossby modes in the subtropics on the zonal propagation of organized tropical convection along the equator (e.g. Madden–Julian oscillation). The candidate with enthusiasm for numerical modelling will employ a hierarchy of models to evaluate nonlinear features of dry and moist Rossby and Kelvin wave dynamics in the tropics and their impact on the mean tropical circulation.
The PhD candidates will be part of the cluster of excellence “Climate, Climatic Change, and Society” (CliCCS ) and be members of our graduate school IMPRS-ESM  which aims to help young academics thrive through all stages of their training. PhD1 and PhD2 will be part of the newly established CliCCS working group on drivers of tropical circulation (link ), which is a joint working group between the University of Hamburg and the Max Planck Institute for Meteorology. PhD3 will be a member of the theoretical meteorology group at the University of Hamburg and coupled to the above CliCCS working group.
