A Tropospheric Water Vapour Climatology And Trends Derived From Vibrational Raman Lidar Measurements Over Switzerland, Shannon Hicks-Jalali

Electronic Thesis and Dissertation Repository

Water vapour is the most effective atmospheric greenhouse gas in terms of warming the atmosphere. Water vapour can magnify the temperature increase that CO₂ would cause alone by 2-3 times. As such, it is critical to monitor changes in water vapour abundance to better understand its role in atmospheric change. I have used 10 years of lidar and radiosonde measurements from the MeteoSwiss research station in Payerne, Switzerland to calibrate the lidar, improve its water vapour retrievals, and finally calculate a lidar water vapour climatology and trend analysis.

Calculating trends with a lidar requires rigorous calibration. Therefore, my first …

Climatology, Variability, And Return Periods Of Tropical Cyclone Strikes In The Northeastern And Central Pacific Basins, Nicholas S. Grondin

LSU Master's Theses

Tropical cyclones (TCs) are among the most destructive meteorological phenomena and impact the lives of people who reside along the coast. The American Pacific Coastline borders the second most active TC development region in the world, the northeastern Pacific (NE Pac) basin. This region, along with the Central Pacific (C Pac)-bordering Hawaii is home to a growing population and cities engaged in a variety of economic activities, most prominently agriculture, fishing, and tourism. This study analyzes fifty-two (1966-2017) years of NE Pac and C Pac TCs through applying track data from the National Hurricane Center’s HURDAT2 and a TC size …

A Climatology Of Quasi-Linear Convective Systems In The U.S., Jacob Adam Strohm

Graduate Research Theses & Dissertations

Quasi-linear convective systems, or QLCSs, are a common, organized thunderstorm mode in the U.S. Over the last fifty years, severe weather research has focused on the supercell, but, recently, QLCSs have become an increasingly important area of study. Researchers and operational meteorologists realize that this morphology is difficult to forecast and may be responsible for a large proportion of the severe weather reports in the eastern two-thirds of the U.S. This study seeks to determine the degree to which QLCSs threaten humans and their assets by, first, assessing their climatology and, second, measuring their contribution to the severe report record. …

Design And Implementation Of The New York State Mesonet Flux Tower Network, Jason Michael Covert

Legacy Theses & Dissertations (2009 - 2024)

The New York State Mesonet (NYSM) was established in 2014 to provide high-quality real-time meteorological data for weather monitoring and forecasting, emergency management, and research aimed at improving numerical weather prediction. The mainstay of the network consists of 126 surface weather stations located throughout New York State with an average spacing of 30 km. In 2017, 17 of the sites (“flux” sites) were equipped with additional (permanent) instrumentation to measure short and long-wave radiation components, soil heat flux, and turbulent fluxes of momentum, sensible and latent heat, and carbon dioxide (CO2). The mesoscale resolution of the 17-site NYSM Flux Tower …
