  • February 22, 2018: Tracking Carbon in The Global Atmosphere: What Have We Learned from Sustained Atmospheric Observations?
    Formal Seminar - Lori Bruhwiler (ESRL/GMD)
    A major uncertainty in projections of future climate is how the carbon cycle will respond to changing climate. Also, human activities have a significant effect on the global land and ocean biospheres, resulting in further impacts on atmospheric composition. Long term atmospheric observations can play a critical role in understanding the sensitivity of the carbon cycle to changing climate and human activities. Sustained observations also can play an important role in evaluating attempts to mitigate greenhouse gas emissions, and spatially distributed observations are essential for attributing emissions to specific regions and economic sectors. Observations from the NOAA Greenhouse Gas Reference Network operated by the NOAA Global Monitoring Division are fundamental to our current understanding of the carbon cycle, and an overview of its operation and findings from analysis of network observations will be discussed. Attribution of changes in atmospheric greenhouse gases to specific regions and processes requires the use of atmospheric models, ranging in complexity from global box models to complex data assimilation/flux estimation systems such as the NOAA GMD CarbonTrackers. Findings from carbon data assimilation systems will be discussed, as well as the challenges of using these systems and the potential for future development.

  • March 7, 2018: Is Climate Change Redefining the Speed Limit of Tropical Cyclones?
    Lunchtime Seminar - Kieran Bhatia (GFDL)
    This study addresses whether recent trends in tropical cyclone (TC) intensification rates can be explained by the natural variability of the climate system or if they are attributable to climate change. Two observational data sources, the International Best-Track Archive for Climate Stewardship (IBTRaCS) and the Hurricane Satellite Data-B1 Advanced Dvorak Technique (HURSAT-ADT), are used to calculate TC intensity changes, normalized by the total number of cases, over the period 1986-2015 and 1982-2009, respectively. In both datasets, Atlantic basin TC acceleration rates significantly increase, which is consistent with the well-documented growth of major hurricanes in this basin. Overall, there are strong positive correlations in most basins but there are significant variations depending on the basin. The trends in the observational datasets are then compared to a pre-industrial multi-century simulation produced by the Geophysical Fluid Dynamics Laboratory (GFDL) High-Resolution Forecast-Oriented Low Ocean Resolution (HiFLOR) model. HiFLOR is a global coupled climate model that is able to simulate and predict category 4 and 5 (Saffir-Simpson scale) TCs and their interannual variations, and is therefore uniquely able to reproduce the entire TC intensification distribution. Monte Carlo techniques are utilized to determine if TC intensification rates are changing in a manner consistent with the natural variability observed in the HiFLOR run or if there is a detectable climate change signal.
