Convective margins theory and variabilityThe near-edge environments of tropical convection zones—or convective margins—are climatologically neither very wet nor very dry; however, convective margins are subject to significant hydroclimatic variability and extremes such as droughts across a range of timescales. The possibility that projected future climate change will strongly impact tropical convective margins, coupled with indications from paleoclimate proxies and simulations of dramatic past changes in these regions (e.g., the African Sahel), make a basic mechanistic understanding of their behavior critical. On-going work in this area focuses on application of process-based, semi-analytic prototypes to interpret convective margins in models and observations and development of diagnostics based on insights from these prototypes to analyze inflow wind-moisture-precipitation relationships over regional convective margins.

Controls on South Pacific Convergence Zone (SPCZ) precipitationThe South Pacific Convergence Zone (SPCZ), an area of intense deep convection and low-level convergence extending southeastward from the western Pacific warm pool into Southern Hemisphere midlatitudes, is a dominant feature of the tropical Pacific. While the existence of the SPCZ has implications for the tropical (and global) climate system, many of its spatiotemporal characteristics, in both observations and state-of-the-art models, are still poorly understood or represented. Current areas of SPCZ research in my group include: (1) NSF-funded collaboration [NSF-AGS-1312865] with PhD student Matt Niznik and collaborator Dr. Ana Maria Duran-Quesada (University of Costa Rica) to analyze high frequency inflow wind-moisture-precipitation relationships along the South Pacific Convergence Zone as simulated in CMIP5 models and the FLEXPART Lagrangian parcel dispersion model; and (2) an NSF-funded collaboration [NSF-AGS-1103209] with Rutgers colleagues Professor Tony Broccoli and postdoctoral associate Damianos Mantsis to investigate spatial changes in SPCZ precipitation and the intensity of the atmospheric general circulation in past climate.

El Niño/Southern Oscillation (ENSO) tropical teleconnectionsMy postdoctoral work with John Chiang (UC Berkeley) focused on elucidating how ENSO affects remote regions of the Tropics, in particular how the ENSO forcing is communicated from the equatorial Pacific to other areas in the Tropics. With PhD student Juan Perez Arango, we are currently analyzing the spatial distribution of ENSO anomalies over tropical South America in CMIP5 models.

Pathways of land-atmosphere couplingThe potential feedback between anomalous soil moisture conditions and precipitation is an important example of land surface-atmosphere coupling, but one which is both difficult to isolate in observations and poorly represented across the ensemble of current generation models. In current NSF-funded collaboration [NSF-AGS-1035986] with Pierre Gentine (Columbia University) and Kirsten Findell (GFDL), along with former postdoctoral associate Alexis Berg, we have been developing metrics for quantifying soil moisture-precipitation feedbacks as they operate in the North American Regional Reanalysis (NARR) and in the GFDL model (AM2.1). In parallel, we have been developing and applying idealized model frameworks for understanding the processes that control the coupling of the land surface and atmosphere, with the principal objective of bridging the gap between theory and observations. In DOE-funded collaboration with Jung-Eun Lee (Brown University), Pierre Gentine, and Joe Berry (Carnegie Institution for Science) as well as collaborators in Brazil, we are evaluating how vegetation processes impact precipitation seasonality and variability in the Amazon. We expect these efforts to lead to improved representation of land-atmosphere coupling in models.

Methodologies for analyzing climate data
The distribution of water vapor in the atmosphere has
important implications climate processes such as radiative
transfer and deep convection. Research in this area
has emphasized relationships between tropospheric water
vapor or trace constituents (e.g., CO), deep convection, and
the vertical and horizontal characteristics of the flow, in
particular how the statistical properties of the pdfs (e.g.,
longer-than-Gaussian "tails") reflect underlying convective
or transport processes. Continuing efforts here are
devoted to quantifying high-frequency, site-level pdfs
(e.g., the Nauru Atmospheric Radiation Measurement climate
observing facility in the western Pacific) in observations
and models. Another recent area of activity, in
collaboration with Dr. Paul Loikith and colleagues at JPL,
involves implementation of pdf-based diagnostics for model
intercomparison. With Master's student Max Pike, we
have begun to use self-organizing maps to evaluate
precipitation features in observations and CMIP5 models.

Spatiotemporal distribution and transport of tropopsheric trace constituentsMy PhD research with Professor Inez Fung (UC Berkeley) focused on identifying the controls on the space and time variability of carbon dioxide and other minor tropospheric constituents ("tracers"), with an emphasis on isolating the role of large-scale circulation and atmospheric transport. More recently, this research area has intersected with other areas of inquiry such as convective margins and tracer pdfs, as we address how insights from tracers may inform understanding of tropospheric circulation, dynamics, and convection.
