Extreme precipitation in the warm season can result from a variety of weather systems, but most such events in the U.S. occur in association with elevated convective systems, in which the unstable air feeding the convection originates above the surface. These events also tend to be poorly predicted by numerical weather prediction models. This presentation will look at past and possible future research directions for both surface-based and elevated mesoscale convective systems (MCSs). Then, the synoptic- and mesoscale processes responsible for the maintenance of elevated, heavy-rain-producing MCSs will be discussed from the perspectives of both traditional composite analysis and a principal component analysis-based method. Quasi-idealized simulations, which incorporate either the mesoscale ascent, or the full three-dimensional variability, in elevated MCS environments, are used to address the respective roles of large-scale forcing for ascent, convectively generated cold pools, and convectively generated gravity waves. Using ensembles of forecasts, we explore the key sensitivities in rainfall amounts to initial conditions and physical processes, and hypotheses identified from the ensemble-based analyses are then tested in a more idealized framework. Finally, remaining limitations in understanding and prediction, along with plans for addressing them in the upcoming Plains Elevated Convection At Night (PECAN) field experiment, will be discussed.

Abstract:
I will present opinions, developed during a varied research-scientist career, on what helps a proposal succeed and what advice might be useful to early-career investigators. My advice is based primarily on my experience as a program office at the NSF but also from other roles in my career, including as a university faculty member, an NCAR scientist, and for almost 10 years a postdoc advisor as director of the Advanced Study Program. The talk will have three main parts: how to develop the project idea, how to develop a detailed project design, and how to avoid common problems when writing the proposal. My comments focus also on suggested ways to use grants to further your career, how to learn about grant opportunities, and how to communicate with program officers. I hope that this talk might be useful to those who expect to seek grants to fund parts of their research.

Abstract:
The tactical approach to funding; eagerly scanning the announcements for something that might work, then repackaging an old proposal to see if it will fit is clearly not working. Success rates have plummeted in the past couple of decades, falling as low as 10% in some disciplines. In this chat and discussion - which will include no overheads - we will consider how to take a more strategic view, developing relationships and establishing new directions. While this takes time to get going, in the long run we shall see it is by far the best approach.

By the Clean Air Act, the U.S. Environmental Protection Agency (US EPA) is required to monitor, regulate and set national ambient air quality standards (NAAQS) for ozone along with other pollutants considered to be harmful to public health and the environment. To investigate ozone exposure, the EPA utilizes monitoring devices sparsely located across the United States along with estimates of gridded ground-level ozone concentration produced by a deterministic numerical air quality model, Models-3/Community Mesoscale Air Quality Model, CMAQ CMAQ. To investigate about the exceedance behavior of ozone relative to the NAAQS which is given in terms of the level of the annual fourth highest ozone concentration, we propose a downscaling modeling approach that employs a spatial fourth highest extreme value (FHEV) model to assimilate both data sources. In particular, the FHEV incorporates spatially-varying parameters that depend on a smoothed CMAQ output. We apply our approach to the annual fourth highest ozone concentration in the Eastern United States during years 2001-2008 and obtain an improved predictive performance compared to that of other downscaler models.

There is a perception that no climate model has simulated the recent plateau of global warming that started around 2000.  This warming slow-down is commonly referred to as the “early-2000s hiatus”.  Though the multi-model ensemble average of uninitialized climate models indeed shows early-21st century warming greater than what has been observed, there are a number of individual ensemble members from several models that did actually simulate the early-2000s hiatus.  Those simulations were successful because the internally generated naturally occurring climate variability associated with the negative phase of the Interdecadal Pacific Oscillation (IPO) happened, by chance, to coincide with the observed negative phase of the IPO that contributed to the early-2000s hiatus.  However, picking out those skillful ensemble members in advance would not have been possible in the 1990s prior to the hiatus, and thus would have had no predictive value.  If the recently developed methodology of initialized decadal climate prediction could have been applied in the 1990s, both the negative phase of the IPO in the early 2000s as well as the hiatus could have been predicted.  The processes associated with this skillful prediction include more heat being mixed into the subsurface ocean as indicated by positive (downward)  net surface heat flux over the global ocean, and stronger Pacific trade winds that intensify the Pacific Ocean subtropical cells and mix more heat into the subsurface ocean.

The Weather Research and Forecasting (WRF) model tutorial will be offered during a two week period from 21 July - 1 August 2014 at the NCAR Foothills Laboratory, Boulder, Colorado.  The tutorial will be divided into 4 sessions:  Basic WRF (21-25 July), WRFDA (28-30 July), WRF Regional Climate (30 July), and WRF Chem (31 July - 1 August). Basic knowledge of atmospheric science and numerical modeling, as well as working in a Unix computer environment, is required. All participants are strongly encouraged to work through one or more of the online tutorials for WRF-ARW, and WRFDA, depending on interest, in advance. Register early, as registration always exceeds capacity.
