The weather pattern has gravely changed over the years and this is not a positive sign. How would today’s weather fare in warmer and wetter situations? Colorado State University researcher Kristen Rasmussen provides new awareness into this question, particularly how thunderstorm fare in a warmer world.
The assistant professor of atmospheric science works at the interface of weather and climate. She is lead author on a new paper in Climate Dynamics that features high aspiration climate replica across the continental United States. Her outcomes propose that paramount thunderstorms, or what atmospheric scientists name convective systems, will rise in prevalence under a warm climate framework. This shift would be engendered by elemental alterations in thermodynamic order of the atmosphere.
For the research, Rasmussen engaged a high powered new dataset developed by the National Center for Atmospheric Research (NCAR) in Boulder, Colorado, where Rasmussen completed postdoctoral work before joining the CSU faculty in 2016.
The scientists engendered the expansive dataset by operating NCAR’s Weather Research and Forecasting model at an exceedingly high resolution of about four kilometers covering the absolute adjacent US. Quintessential climate models only resolve to about 100 kilometers, not virtually the feature obtainable in the new dataset. Encompassed in the new data are finer-scale cloud processes which have been absent in the antecedent climate models.
Utilizing the data set and cooperating with NCAR researchers, Rasmussen led analysis of detailed climate reproductions. The premiere control simulation involved weather patterns from 2000-2013. The second simulation surfaced the similar weather data with a pseudo global warming capability utilizing a tried and tested scenario that presumes a 2- to 3-degree raise in the usual temperature, and a magnifying a of atmospheric carbon dioxide.
