Abstract. The Atmospheric Radiation Measurement (ARM) West
Antarctic Radiation Experiment (AWARE) provided a highly detailed set of
remote-sensing and surface observations to study Antarctic clouds and
surface energy balance, which have received much less attention than
for the Arctic due to greater logistical challenges. Limited prior Antarctic
cloud observations have slowed the progress of numerical weather prediction
in this region. The AWARE observations from the West Antarctic Ice Sheet (WAIS) Divide during December 2015
and January 2016 are used to evaluate the operational forecasts of the
Antarctic Mesoscale Prediction System (AMPS) and new simulations with the Polar
Weather Research and Forecasting Model (WRF) 3.9.1. The Polar WRF 3.9.1 simulations are conducted with the WRF
single-moment 5-class microphysics (WSM5C) used by the AMPS and with newer
generation microphysics schemes. The AMPS simulates few liquid clouds during
summer at the WAIS Divide, which is inconsistent with observations of frequent low-level
liquid clouds. Polar WRF 3.9.1 simulations show that this result is a
consequence of WSM5C. More advanced microphysics schemes simulate more cloud
liquid water and produce stronger cloud radiative forcing, resulting in
downward longwave and shortwave radiation at the surface more in agreement
with observations. Similarly, increased cloud fraction is simulated with the
more advanced microphysics schemes. All of the simulations, however, produce
smaller net cloud fractions than observed. Ice water paths vary less between
the simulations than liquid water paths. The colder and drier atmosphere
driven by the Global
Forecast System (GFS) initial and boundary conditions for AMPS forecasts produces
lesser cloud amounts than the Polar WRF 3.9.1 simulations driven by
ERA-Interim.
