Formation and maintenance of tropical cyclone spiral bands in idealized numerical simulations
(Massachusetts Institute of Technology, 2019)
Spiral bands are one of the most prominent features of tropical cyclones (TCs). These regions of clouds and rainfall are often the source of major TC hazards, such as inland flooding, mudslides, and tornadoes. Since the ...
The tropopause region thermal structure and tropical cyclones
(Massachusetts Institute of Technology, 2018)
This thesis is an exploration of two seemingly unrelated questions: First, how do water vapor and ozone variations radiatively influence the thermal structure of the tropopause region? Second, what sets the thermodynamic ...
Estimating regional nitrous oxide emissions using isotopic ratio observations and a Bayesian inverse framework
(Massachusetts Institute of Technology, 2018)
Atmospheric nitrous oxide (N₂O) significantly impacts Earth's climate due to its dual role as an inert potent greenhouse gas in the troposphere and as a reactive source of ozone-destroying nitrogen oxides in the stratosphere. ...
Dependence of continental severe convective instability on climatological environmental conditions
(Massachusetts Institute of Technology, 2017)
Most of Earth's strongest atmospheric convection occurs over the continents, where potential energy is stored over time in metastable vertical profiles, only to be released rapidly by severe storms. In contrast to ...
Fundamental aerosol-cloud interactions and their influence on the aerosol indirect effect on climate
(Massachusetts Institute of Technology, 2017)
The influence of anthropogenic aerosol emissions on the optical properties of clouds and the radiative forcing arising from these interactions, known as the aerosol indirect effect on climate, constitutes a fundamental ...
