Question 5. Look at the radar reflectivity image at 4:30. How does this plot and the location of the
echoes relate to the Mesonet fields at the same time?

Answer. At 4:30 p.m., two complexes of storms are evident on the radar image, along with two thin lines. In northern Oklahoma, the cells have formed along the triple point, or low pressure center. The cold front shows up nicely in the Mesonet temperature field and as a thin line in the radar image. In central Oklahoma, another thunderstom has formed near the dryline bulge. The dryline does not show up as well in the 4:30 p.m. color-filled Mesonet plot, because of the automated computer analysis required to make that plot. Compare the color-filled plot with the line contours and the dew point station plot to obtain a better understanding of the position of the dryline. Note the dew point value at the El Reno Mesonet site which was not handled well by the computer analysis program. |
