of Proposed Work: We will perform a scaling analysis of terrestrial carbon exchange using several of the NIGEC flux sites in different biomes (forest, C 4 grassland, C 3 agriculture), using a numerical model of the biophysics and biogeochemistry of plants and soils (SiB2), which includes calculations of the surface fluxes of CO 2 , energy, and moisture. This model will be used to analyze local ...

Rising atmospheric CO(2) levels are predicted to have major consequences on carbon cycling and the functioning of terrestrial ecosystems. Increased photosynthetic activity is expected, especially for C-3 plants, thereby influencing vegetation dynamics; however, little is known about the path of fixed carbon into soil-borne communities and resulting feedbacks on ecosystem function. Here, we exam...

Low-pressure, low-temperature plasmas are widely used for materials applications in industries ranging from electronics to medicine. To avoid the high costs associated with vacuum equipment, there has always been a strong motivation to operate plasmas at higher pressures, up to atmospheric. However, high-pressure operation of plasmas often leads to instabilities and gas heating, conditions that...

The regional climate response to radiative forcing is largely controlled by changes in the atmospheric circulation. It has also been suggested that global climate sensitivity depends on the circulation response, an effect we call the “atmospheric dynamics feedback”. Using a technique to isolate the effect of changes in atmospheric circulation on top-of-atmosphere (TOA) radiation, we calculate t...

[1] The marine production, cycling, and air-sea gas exchange of nitrous oxide (N2O) are simulated in a coupled climate-biogeochemical model of reduced complexity. The model gives a good representation of the large-scale features of the observed oceanic N2O distribution and emissions to the atmosphere. The transient behavior of the model is tested for the Younger Dryas (Y-D) cold period (12,700–...

Floods have repeatedly battered the South Indian state, Kerala, as a result of unprecedented heavy rainfall during Boreal Summers, in recent years. The state witnessed large departures from normal 2018 and 2019. Previous studies seldom adopted systematic approach to understand phenomenon responsible for recurrent extreme events. Hence, this study, based on spectral methods, identifies character...

In this paper the effect of a summer Mistral event on the Ligurian and Tyrrhenian Seas in the northwestern Mediterranean is discussed, using a coupled numerical model and satellite and in situ observations. The focus is on the spatial and temporal distribution of the ocean mixed layer response to the strong winds, and on how this is affected by atmosphere–ocean coupling. The model used is the C...

Warmer SST and more rain in the Northern Hemisphere are observed year-round in the tropical eastern Pacific with southerly wind crossing the equator toward the atmospheric heating. The southerlies are minimal during boreal spring, when two precipitation maxima straddle the equator. Fourteen atmosphere– ocean coupled GCMs from the Coupled Model Intercomparison Project (CMIP3) and one coupled reg...
