An Integrated View at the High Latitude Atmospheric Boundary Layer & Surface Atmosphere Interaction

Javier Fochesatto
Professor of Atmospheric Sciences University of Alaska Fairbanks

Surface-atmosphere interactions are central to understanding current and future trends in weather and climate. Large-scale surface fluxes are the quantities often required for model input and/or validation. However, this research is challenging because it involves the analysis of turbulence data that is best understood only under specific surface and atmospheric boundary layer (ABL) conditions, and is often limited to specific levels within the ABL. Such ideal conditions are not always representative of the local surface and flow properties, nor of the spatial and temporal variation of fluxes owing to those properties. Even within what may be classified as the same surface type, local flux values can vary considerably. Quantifying the relationship between local and large-scale fluxes and their connection to surface properties and ABL-flow regime has been the motivation for numerous field campaigns and remains an unsolved problem. In this seminar, I will describe new observational platforms and methodologies that apply to ABL research and surface turbulent fluxes. I will discuss Boundary Layers and surface fluxes in the most vulnerable ecosystems on earth, the Arctic Tundra and Boreal Forest. I will close this seminar by sharing my strategic research plan in the area of land surface atmosphere interaction and its application to current problems in atmospheric sciences.

Biosphere-atmosphere Exchange: Insights from Measurements and Models

Edward G. Patton
National Center for Atmospheric Research

Forests cover a significant fraction of Earth’s land surface and play a critical role in Earth’s climate through their influence on energy, water, and carbon cycles, as well as through exchanges of reactive species that place stringent controls on the atmosphere’s oxidative capacity [or cleansing ability]. For these reasons, understanding the processes controlling turbulent exchange of energy, momentum, and scalars between the vegetation and the atmosphere has never been more important. Vegetation canopies produce turbulence that is qualitatively different to that over a rough surface, which ultimately results from canopies absorbing momentum over a distributed height range rather than at the ground surface. Within the canopy airspace, the distribution of the mean velocity and the turbulence is controlled by the interplay of downward turbulent transport of momentum and canopy drag modulated by diabatic influences. The aerodynamic drag of the canopy varies spatially based upon the distribution of the canopy elements, their efficiency at extracting momentum, and the velocity field itself. Similarly, the balance between turbulent transfer and the distribution of scalar sources and sinks determines within-canopy distributions of scalars like heat, water vapor, and carbon dioxide. These, in turn, respond to solar radiation as it attenuates through the foliage, the biological state of the plants (e.g., their access to soil water), the ambient concentration of the particular scalar in the canopy airspace, and, in the case of reactive scalars, their reaction rates. Current theory describing canopy exchange largely hinges on the hydrodynamic instability associated with an inflection point in the vertical profile of the horizontal wind at canopy top (sometimes called an inflection-point instability) induced through the canopy’s distributed momentum absorption. Parameterizations built upon this theory are showing great promise in predicting flux–gradient relationships in a canopy’s vicinity. However because the theory relies on the presence of wind speed shear at canopy top, its applicability across the broad stability variation that occurs outdoors remains uncertain. Utilizing a combination of measurements and models, this talk will: 1) present our current understanding of biosphere-atmosphere exchange, 2) highlight some new insights into atmospheric stability’s role in determining the spatial structure and distribution of motions controlling turbulent transfer at the canopy- atmosphere interface, and 3) discuss implications for parameterization of biosphere-atmosphere exchange in weather and climate models.

In-Situ Measurements in Hurricane Environments

Joseph J. Cione
NOAA/AOML/ESRL

The significance of the atmospheric boundary layer on tropical cyclone formation, maintenance and intensity change is well known. It is here where the strongest winds are found and where ocean-atmosphere exchanges of heat, moisture and momentum occur. However, largely due to weather-related safety concerns and platform unavailability and survivability, limited detailed information is known about this turbulent environment. Using a mix of tropical cyclone data taken from 100’s of air-sea buoys, measurements from recent unmanned aircraft experiments and observations from sea surface temperature capable GPS dropsondes, analyses will be presented that look to extend the current body of knowledge associated with this critically important, yet difficult to observe region of the storm.

UCAR Staff,

Effective 10/1/16, you will NO longer have to enter a charge code to make a work-related long distance call from your office and conference room phones.  Work-related long distance charges are covered for UCAR by the Communications Pool. This change results in efficiencies in technology deployment, support, and telephone system management.  Personal long distance service from your office and conference room phones was removed 6/1/13.  ReadyTalk accounts will still require a charge number.

Per the UCAR Policy:  3-6 ACCESS TO AND USE OF COMPUTER AND INFORMATION SYSTEMS

https://www2.fin.ucar.edu/policies/3-6-access-and-use-computer-and-information-systems

“Employees may use some UCAR computer and information systems, such as telephones, computers, internet access, and facsimile and copy machines, for limited and reasonable amounts of personal use.  Employees are prohibited from personal long distance activities using UCAR telephones and facsimile machines. In no event does personal use include activities related to operating a personal business or any activity that would violate any UCAR policy. Use of UCAR's computers to access inappropriate Web sites, including pornography, subjects the user to disciplinary action up to, and including, immediate termination.”

Questions can be sent to:  marla@ucar.edu

Thanks
Marla Meehl - Manager of the Network Engineering and Telecommunications Section (NETS)

Operations begin @ 06:00 on October 8th and are scheduled to end @ 18:00 on October 8th. Program system administration teams have been provided details on the work taking place. If you have questions regarding impacts to your program, check with your system administration team. If you require additional information send your questions to: cislhelp@ucar.edu.

CISL Service Outage Information:

  • NETS MLDC 10G Ethernet switches will lose connectivity while NETS reconfigures ml-mr-j1-es.  All other  Ethernet switches in the MLDC and in other areas of the Mesa Lab will remain up and connectivity will be available.  The work on ml-mr-j1-es affects ml-mr-j2-es, ml-mr-j3-es, ml-mr-c7-gs, ml-mr-c9-gs, and ml-mr-c5-gs. The planned window for this work is 6:30 a.m. to 8 a.m.
  • —DNS: Internal DNS servers at ML are expected to remain up except for dnsi1 (128.117.64.44). External DNS servers at ML will be temporarily unavailable between 6:30-9am and dnsx1 (192.43.244.39) will remain down for the duration of the power down. DNS master servers, the remaining slave servers, and DNS servers at NWSC will remain up. DNS interruptions and slowness should be minimal assuming devices are configured to also resolve DNS queries with other servers. Infoblox hosted DNS and DHCP will failover to the NWSC node.
  • The license servers for Mathematica and the PGI compilers will be down. However, Matlab on Yellowstone WILL NOT be affected because it uses a different license server for Matlab.
  • —UCAR web services: jira, drupal sites and wiki.ucar.edu will be down.
  • —ExtraView (CISL Help Desk ticketing system) will be down. - Please contact CASG at x4300 or 307-996-4300.
  • ML Active Directory Domain Controller: Windows CIT domain authentication should remain unaffected as two other domain controllers at different sites will be up.
  • Cisco Anyconnect VPN will remain up, but without redundancy.
  • colopower.ucar.edu - Will be unavailable from 06:30 - 08:00.
  • The CrashPlan backup service will be down during this time for both internal and external use
