Tomorrow is the launch of our modernized umbrella websites for NCAR and UCAR!

The new umbrella sites are designed to make it easier for external audiences to understand what we do, why it matters, and the partnership between NCAR and UCAR. The new design also responds to the size of a user’s screen, so it works well on phones, tablets, and other devices.

Existing lab and program websites, along with HR and administrative and operations sites within UCAR (e.g. Contracts, IT, Finance, FMS&S), will remain the same for now. remain as they are for now. You may also notice that some of the content aimed at staff that was on the old UCAR and NCAR umbrella sites has been moved to internally facing websites. If you are having trouble finding what you are looking for, we recommend visiting https://staff.ucar.edu/for-staff for a list of frequently accessed links. You can also use the search feature on the umbrella sites to find internal content.

We know there may be some minor issues, including broken links. Thanks in advance for your patience as the team works through those in the first couple of days. If you have questions or detect problems after site launch, please use this form (https://docs.google.com/forms/d/e/1FAIpQLSftMNY4BNFfc24Fev_48dea8asnla30...) to share them with the project team. 

If you didn't get the chance to attend one of the Information Sessions hosted by the Web Modernization Project Team in July, here is a link to the recording and a preview of the sites that will launch tomorrow:

Next steps The Web Modernization Project Team has been charged by the President’s Council with developing a project plan with resource requirements to implement the new design standards and develop the content strategy for the NCAR lab and program external websites.

To prepare for this plan, the team will be working with relevant staff stakeholders and Vermilion — the design and digital marketing consulting group we partnered with on the umbrella sites — to conduct a web needs review of the NCAR lab and program sites. This needs review will:

Educate staff stakeholders about the new visual identity standards and proposed content strategy Engage staff stakeholders in a solution design for a “commons” area and NCAR lab/program sites Determine shared and unique requirements and resources Develop a project schedule

The review of the NCAR lab and program sites will kick off with a presentation to the NCAR Executive Committee on Tuesday and then involve staff in focus groups and input opportunities. We will have the results later this year to inform the development of the phase 2 web modernization project plan. For questions about the project please contact Rachael Drummond, Helen Moshak or Nate Wilhelmi.

The Sundowner Winds Experiment (SWEX) First Intensive Campaign: understanding downslope windstorms in the Santa Ynez Mountains, Santa Barbara, CA

Sundowner winds (Sundowners for short) are the northerly gusty winds frequently observed leeward of the Santa Ynez Mountains (SYM) in coastal Santa Barbara (SB), CA. These winds typically peak from early evening through early morning with gale force gusts exhibiting features of downslope windstorms. The SYM rise abruptly from coastal SB separating the Pacific Ocean on its south face from the Santa Ynez Valley on its north face. Sundowners are considered the most relevant fire weather condition in all seasons and represent a major hazard for aviation, particularly small crafts. All major wildfires affecting the region exhibited significant fire spread rates toward the SB wildland-urban interface during Sundowners. The Sundowner Wind Experiment-first intensive campaign (hereafter, SWEX-I) was the first to evaluate vertical profiles of winds, temperature, humidity and other thermodynamic variables from the boundary layer to mid-high troposphere and leeward of the SYM during episodes of Sundowners (wind gusts exceeding 13 m/s or 30 mph). This was accomplished by launching 3-hourly radiosondes during the Sundowner events on April 28-29, 2018. SWEX-I demonstrated that cross-mountain winds in the lee of the SYM exhibit complex spatial and temporal patterns. Profiles of wind speed and direction, temperature and humidity near ground level showed a transition from humid onshore winds from morning-to-mid afternoon hours to very pronounced offshore winds during the evening. These offshore winds accompanied a northerly nocturnal low-level jet leeward of the SYM with variable behavior. The experiment showed evidence of mountain waves and critical layers associated with the intensification of winds. Around sunset (April 28, 20:00 PDT), the jet was characterized by a layer with strong wind speeds (~17m/s) around 273m asl. Winds weakened considerably at 23:00 PDT (peak ~ 9. 5m/s at 186m asl) but enhanced dramatically at 2:00 PDT on April 29 (peak ~14 m/s) at much lower elevations (150asl), when the jet was confined to a much narrower layer compared to observations at 20:00 PDT. These transitions were accompanied by changes in stability profiles and the Richardson number. Additionally, we examined the skill of the Weather and Forecast Model (WRF) (at 1km grid spacing) in forecasting this event, with focus on profiles of winds and stability. These results advanced our understanding of Sundowners and indicated that a comprehensive field campaign is critical to properly characterize the main mechanisms driving these winds and to advance studies on predictability of these events.

Satellite Wind Data Assimilation in HRRRAK-like Model

Jiang Zhu University of Alaska

High-Resolution Rapid Refresh for Alaska (HRRR-AK) model is one of the NOAA operational convective scale forecast system. Satellite wind data are not assimilated in the HRRR-AK model. Thanks to its high latitude, Alaska benefits from many polar-orbiter passes each day. Wind data derived from satellite observations have a good potential to improve the HRRR-Alaska short-term forecast. The purpose of the research is to investigate if the assimilation of satellite wind data can improve accuracy of the HRRR-AK model forecast. Experimental environment was setup in AWS cloud system, as well as the local machine in University of Alaska. The experimental model is HRRR-like model. It uses similar configuration, parameters, and initial fields as HRRR-AK model. In the experiment, the model run in three modes. Control run does not assimilate any observation data. Two experiment runs, one assimilates wind data only, and one assimilates wind data plus conventional observation, respectively. For simplicity, GSI 3D-Var analysis is used in the data assimilation experiments. The case study shows that valid VIIRS wind data is coarse in the domain; the impact of data assimilation of VIIRS wind data is very limited. The WRF model configured like HRRR-AK (smaller domain size and grid resolution) was used to do 24-hour forecasts 4 times daily. A month of forecasts are analyzed in terms of RMSEs. The preliminary conclusion shows that the VIIRS wind data does not improve the HRRR-AK-like model short-term forecast due to very coarse data distribution in the model domain. Further study includes evaluation of assimilation of all available satellite-derived wind data into the model.

ACOM SEMINAR

TITLE:  Changes in transport and mixing of polar ozone during sudden stratospheric warmings

PRESENTER:  Álvaro de la Cámara, Universidad Complutense de Madrid

ABSTRACT:  Understanding the impact of dynamical processes such as sudden stratospheric warmings (SSWs)  on Arctic ozone is key to interpreting the observed interannual variability and better quantify polar ozone evolution. In the first part of this seminar, we will focus on quantifying the changes in the stratospheric circulation and the mixing properties of the flow during SSWs. Using 34 years of reanalysis data (ERA-Interim), and 240 years of output from the Whole Atmospheric Community Climate Model version 4 (WACCM4), we find: i) A weakened residual circulation and intensified isentropic mixing after the onset of SSWs that persist for more than two months in the lower stratosphere; ii) sufficiently deep SSWs (i.e. those followed by Polar-night Jet Oscillation events, or PJO) have a stronger and more persistent response in the meridional circulation and isentropic mixing; and iii) long after the strong wave forcing that drives the SSWs has declined, diffusive fluxes of potential vorticity (PV) remain anomalously high in the lower stratosphere delaying the recovery of the vortex.

In the second part of the seminar, we will explore how these alterations in the circulation affect Arctic ozone. The composite evolution of ozone displays positive mixing ratio anomalies up to 0.5 – 0.6 ppmv above 550 K (∼50 hPa) around the central warming date and negative anomalies below (-0.2 to -0.3 ppmv), consistently in observations, reanalysis and model. We will show the fundamental role of irreversible mixing of ozone in delaying the recovery of climatological values, and contributing to maintain the ozone anomalies in the lower stratosphere over 2 to 3 months after the occurrence of SSWs.
