As Hurricane Ingrid continued to move westward in the Bay of Campeche toward a landfall in Mexico (the Mexican coast is visible as black line to the left in the images) a NOAA P-3 mission collected data to study the impact of shear on tropical cyclones. Included here you see images of the horizontal winds within 300 km of Ingrid sampled from the tail Doppler radar on the P-3 during evening of 15 September, 2013. These images are at three altitudes (1 km, 3 km, and 6 km) using a composite of winds from the P-3 Doppler pattern around Ingrid. Also plotted on the each analyses are the locations of dropwindsondes deployed by the P-3 (plotted using standard station symbols). These analyses show that Ingrid maintained a symmetric distribution of precipitation at all altitudes shown, with the bulk of the precipitation surrounding the center. It appears that there is a circulation center at all altitudes with a radius of maximum wind speed of around 35 km. As in the previous G-IV mission, the wind field appears to have spread out to the north and northeast of the center and is not as asymmetric as previously, but with the stronger winds still to the north of the circulation center. Below 3-km altitude the centers seem nearly vertically aligned. However between 3- and 6-km altitude the circulation appears to tilt 10-15 km to the north-northeast indicative of continued southerly shear.
