Fig. 1a: Example output from thunderstorm cluster tracking algorithm. Tracks are based on centroid positions for past 3 hours. Cluster number (green) and the beginning and ending time (yellow) are shown. Users can replot tracks using different cloud top temperature thresholds and enhance the image (Fig. 1b) to highlight cloud clusters defined by those thresholds. By successively choosing lower temperature thresholds, it?s possible to isolate and track overshooting tops.
Fig. 2: Example output from real-time satellite winds web page: high density wind vectors from automated feature tracking algorithm. Uses 30 minute GOES water vapor imagery (6.7 micron). Each wind vector is assigned a layer height based on the observed radiance and vertical weighting function (black: 100-250 mb, cyan: 251-350 mb, yellow 351-500 mb).
Fig. 3: Example output from real-time satellite winds web page: contours of divergence at 300 mb from an objective analysis which combines winds from the satellite algorithm and a first guess model (NOGAPS) in green, and from the RUC-II analysis in red. Note the divergence (positive values) associated with the convective complexes in the Dakotas and Oklahoma. In general, the RUC-II analysis has smaller-scale structure owing to its high resolution. In some locations, there are also significant differences in the location & magnitude of divergence/convergence centers.
Fig. 4: Same as Fig. 2, except 1 hour later. Note the weakening divergence associated with the decaying convection in eastern Oklahoma. Also, strong convergence is evident behind the system where upper level drying has occurred.
Storm total precipitation estimated in Arizona from multisensor 88D/GOES
algorithm (from J.J. Gourley). Image on left shows the spatial distribution
of estimated preciptation and locations of rain gages. Scatterplot at upper
right compares the estimated values with gage measurements. Statistics
shown in the table at lower right indicate significant improvement of the
multisensor technique over radar only estimates.
