ABSTRACT
This study investigates the evolution of the Great Plains nocturnal low-level jet (NLLJ) as warm, moist flow returns following a cold frontal passage. The study utilizes the ERA-5 reanalysis and 3-h radiosonde data taken during the International H2O Project field campaign. This talk will present new insight into the processes controlling the NLLJ intensity and structure including the possible role of variations in water vapor and radiative processes. The results also show that two mechanisms resulted in the destabilization of the nocturnal environment, weak (2 cm/s) ascent and differential advection, with implications for the eastward movement of nocturnal convection over the region.
If you have any questions about the seminar, reach out to Jacquie Witte or Melissa Ward.
