On Dynamical Impacts on Stratospheric Water Vapor Trends Above Boulder, Colorado

Long-term stratospheric water vapor (SWV) trends above Boulder, CO, (40°N, 255°E) are generally positive and slightly larger than those for zonal average SWV. This study finds a slight enhancement for SWV at 31.6 hPa above Boulder from middle February through March 1979, as seen in the satellite dataset from the LIMS instrument. That excess of SWV correlates well with air in the polar vortex that underwent an elongation and splitting in middle February following a final stratospheric warming event. Zonal wave-2 events tend to occur in late winter, but not every year. Such aperiodic variations in data time series of SWV may affect the fitting of its linear trend term.
