Using the WRF Model to Investigate Climate Change Influence
on the Track and Intensity of Hurricane Sandy

Gary M. Lackmann
Department of Marine, Earth, and Atmospheric Sciences
North Carolina State University
Developmental Testbed Center, August 2014

Hurricane Sandy was associated with historic societal impacts when it made landfall
along the New Jersey shore in late October 2012. The event generated vigorous
discussions as to whether the severity, or perhaps occurrence, of the event was tied to
anthropogenic climate change. Two related questions are (i) whether the frequency of
this type of event is altered by anthropogenic climate change, and (ii) if the synoptic
pattern accompanying Hurricane Sandy had taken place 100 years ago (or 100 years in
the future), how would the track, intensity, and impacts have differed? Here, we
investigate question (ii) using a simplified approach that is designed to quantify the
storm-scale changes attributable to large-scale thermodynamic changes. First, hypotheses
are presented as to how and why we would expect climate change to alter Sandy’s track
and intensity. An ensemble of WRF model simulations, in conjunction with GCM derived
large-scale thermodynamic changes, is used to analyze changes between current, past, and future versions of Sandy.


The impact of climate change on the synoptic steering features suggests offsetting
processes. Warming and increased precipitation/condensational heating would strengthen
the downstream ridge to the north of Sandy, resulting in stronger westward motion.
Diabatic weakening of an upper-level trough to the south of Sandy would have the
opposite effect. Increased upper-level westerly flow would lead to more progressive
synoptic features, suggesting a more eastward track with warming. Numerical
experiments are required to determine which effect, if any, dominates. For this
presentation, I will explore some of the WRF features that enable skillful simulations of
the storm. Results indicate that climate warming to date had limited effect on the
observed Sandy, but that projected future warming would result in a significantly
stronger storm with a more northward landfall location. Research to date has not directly
addressed the question of climate-change influences on Sandy’s genesis or early track
evolution.

Human Subjects Research Training at UCAR: An Overview of the UCAR Process

Date/Time: September 9, 2014 from 10am - 11am
Location: FLA-2111 and via webinar

Required training for researchers and administrators on the purpose, procedures and regulations governing human subjects research will be provided this year on Tuesday, September 9. The training will be conducted by Meg McClellan, UCAR General Counsel and member of UCAR's Human Subjects Committee. This training is open to all staff, with emphasis on researchers and administrators involved in human subjects research.

This one-hour seminar will provide UCAR-specific information for researchers.  In advance of this UCAR-specific training on September 9, it is recommended that you also complete a general human subjects on-line training provided at the National Institute of Health web site:

Cirrus cloud formation and evolution from the microscale to the synoptic scale

Minghui Diao

NCAR Advanced Study Program (ASP)

Earth Observing Laboratory

Cirrus clouds, covering ~30% of the Earth’s surface, play important roles in Earth’s climate, weather and atmospheric chemistry. As a major uncertainty in climate models, the magnitude and sign of cirrus clouds’ radiative forcing (cooling or warming) are influenced by both their microphysical properties (such as ice crystal number density and size distribution) and the larger scale characteristics (such as horizontal and vertical extent). However, it is challenging to understand these multi-scale processes due to the limited spatial and temporal coverage of in-situ observations.

In this work, we link in-situ observations with the meteorological background using reanalysis data. Two formation mechanisms are found for cirrus clouds’ initial conditions - ice supersaturation. These two mechanisms show different dynamical conditions (large scale uplifting versus small scale waves/turbulences), as well as mixing of different air masses (tropospheric mixing versus stratospheric-troposphere mixing). Jet stream and the extratropical tropopause are found to play important roles in setting these dynamical conditions.

Besides the regional analyses, we conduct a hemispheric comparison on cirrus cloud formation and evolution (Diao et al. 2013, 2014). Our work is motivated by the question of “are there any differences in cirrus cloud formation and evolution, given that the Northern Hemisphere has ~10 times higher aerosol loading than the Southern Hemisphere?” Comparisons of relative humidity, ice crystal number density and mean diameter, as well as the relative lifetime of cirrus will be shown.
