Stratosphere - troposphere interaction during stratospheric sudden warming events
The stratosphere and the troposphere exhibit a strong coupling during the winter months. However, the coupling mechanisms between the respective vertical layers are not fully understood. An idealized spectral core dynamical model is utilized in the present study in order to clarify the coupling …

The Changing Role of Reactive Nitrogen in the Troposphere
… budget of reactive oxidized nitrogen in the troposphere using a state-of-the-science chemical transport model, and observational constraints for this budget from remote troposphere flight campaign data. We also provide modeled estimates for the chemical fluxes between key NOy species, finding …

Dynamical and radiative processes in the Upper Troposphere/Lower Stratosphere
… key attributes and processes in the Upper Troposphere/Lower Stratosphere (UTLS). This work involves exploring the interactions between radiation and dynamics which ultimately affect the destination of chemical constituents. A recently identified feature of the extratropical upper …

Last-saturation applications to the humidity of the subtropical middle troposphere
… During El Nino northern winter, the free troposphere over the subtropical north Pacific is both drier and warmer than during La Nina. For instance, during El Nino (La Nina) northern winter, 57% (49%) of the air at 20˚N and 633 hPa over the north Pacific was last saturated poleward of 20˚N …

Short meridional scale anomalies in the lower stratosphere and upper troposphere
… shows maxima in the lower stratosphere and upper troposphere with a node between these maxima in the 200 to 400 mb region. The SMSA are not regularly propagating features. They are found to be episodic, with an episode lasting from 1 to 3 weeks;In addition to the temperature structure, the SMSA …

Tracer-Independent Approaches to Stratosphere-Troposphere Exchange and Tropospheric Air Mass Composition
… the interaction between the stratosphere and the troposphere. We perform the first analyses of stratosphere-troposphere exchange using one-way flux distributions; diagnostics are illustrated in both idealized and comprehensive contexts. By partitioning the one-way flux across the thermal …

Effects of the troposphere upon radio communications and implications for weather measurement
The aim of this research is to use observations of Very High Frequency (VHF) radio wave propagation to estimate the refractive index of air over a propagation path and subsequently the pressure, temperature, and water vapour. This can be accomplished by transmitting a known signal from one spatial …

Eurasian Snow Cover and the Role of Linear Interference in Stratosphere-troposphere Interactions
… and a negative NAM response that couples to the troposphere. It is shown that unexplained aspects of the evolution of this response can be clarified by examining the time evolution of the phasing, and hence the linear interference, between the wave response and the background climatological wave. …

Volatile organic compounds in the New England troposphere: Atmospheric chemistry and measurement techniques
<p>Atmospheric measurements made at Appledore Island, Maine were used to investigate nighttime nitrate radical (NO3) chemistry and its significance for the nitrogen oxides (NOx = NO + NO2) budget in the Gulf of Maine region during the summer of 2004 International Consortium for Atmospheric Research …

Response to stratospheric forcing and its dependence on the state of the troposphere
There is increasing evidence that changes in the stratosphere can have an impact on the surface. While observational results show a surface response of about 0.5 - 1 m/s, modeling studies can show a signal two times and in a particular extreme, four to eight times larger. In this thesis, an …

Alternative metrics for measuring heating trends, with possible connections between the surface and troposphere
… compare favorably to reanalysis data. The upper troposphere indicates cooling, while the lower troposphere is neutral or slightly warming. Comparisons of tropospheric and surface trends for the eastern United States show similar seasonal patterns. Lower-tropospheric trends in the eastern United …
