Overcoming the Barrier to Extended Range Prediction over the Arctic

For a variety of reasons, small but intense cyclones are very poorly predicted over the Arctic even by the most skillful NWP models. The inability to predict this forcing is a predictability barrier that must be overcome if intra- and interseasonal predictions of sea ice are to become a reality. The overarching objective of this DRI is to gain a new understanding of the basic processes governing the development and evolution of Arctic cyclones as well as their relationship to tropopause polar vortices (TPVs) and their influence on coupled air-sea-ice processes.

Scientific Issues
Supported investigations focus on the understanding Arctic cyclones, their mesoscale attendant features (e.g., low-level jets, fronts, tropopause folds), polar lows, and TPVs through theory, simulations, observations and model development. Besides identifying the shortcomings of current NWP models, a goal is to identify methods to improve the skill of future NWP systems. The following are examples of some research topics that are envisioned to address the overarching scientific issues related to improving prediction of these phenomena:

  1. Can multi-scale modeling systems be used to bridge the climate/weather domain inhabited by Arctic cyclones and TPVs and increase predictability of this seasonal driver of smaller scale forcing events?
  2. What factors influence the predictability of Arctic cyclones and what are the most important parameters and observations required for skillful forecasts of high-latitude cyclones and smaller-scale polar lows?
  3. How do air-sea-ice interaction processes occurring at the lower boundary respond to the influence of Arctic cyclones? How does the ocean-ice boundary morphology influence polar low genesis?
  4. What processes contribute to the intensification, properties, precipitation, and evolution of Arctic cyclones and their interactions with clouds and the boundary layer?
This DRI is expected to run for five years, from FY18 to FY22.

DRI Kick-Off Meeting Outcomes: Research Areas

May 30-31, 2018

The Arctic Cyclone DRI kick-off meeting took place in Monterey, CA on May 30-31, 2018. Over the two day meeting, the PIs presented their proposed projects and discussed future avenues of collaboration.

Four key research areas were highlighted:

  1. Mesoscale strucutre and dynamics (from the troposphere to the lower stratosphere) of TPVs, Arctic Cyclones, and Polar Lows
  2. Interaction of TPVs, Arctic Cyclones and Polar Lows with sea ice, the Arctic boundary layer and near surface phenomena and processes
  3. Synoptic-planetary and extratropical-Arctic interactions and impacts on TPCs, Arctic Cyclones, and sea-ice extend
  4. Coupled prediction, data assimilation and predictability for the Arctic

About the DRI

This ONR Departmental Research Initiative (DRI) is to enhance the understanding of dynamics of Arctic cyclones and their relationship to the tropopause polar vortex (TPV).

The DRI is motivated by recent studies which lent support to the hypothesis that year-to-year variations in sea ice are driven to a great extent by a relatively small number of intense storms—Arctic cyclones.
