Tropical Storm Pali has formed in the central Pacific, in a region east-southeast of Kwajalein Atoll (which atoll is at 9 N, 168 E), just west of warm Sea Surface Temperature anomalies (Source) associated with the ongoing El Nino. The Himawari animation, above, of the 6.2 Water Vapor imagery from 0000 UTC on 7 January through 1500 UTC 8 January 2016 (mp4 available here), shows impressive upper-level outflow from the region of convection surrounding the storm center. The Composite Infrared Imagery, below, shows the slow but steady organization of the storm. Infrared brightness temperatures are very cold, with temperatures occasionally colder than -95 C.

Pali is forming in a region that allows views from both GOES-15 (overhead at the Equator and 135 W) and Himawari-8 (overhead at the Equator and 140 E). The animation below shows GOES-15 at Full Resolution from the Full Disk Imagery that is used to view Pali. Note that Himawari data has been degraded both spatially and temporally in the animation.

An animation that is at full resolution for Himawari-8, for just 3 hours, from 0600-0900 UTC, is below. Only two GOES-15 Images are available during this loop that includes 19 Himawari-8 images. (Note also the increase in spatial resolution with Himawari, from 4 km for GOES to 2 km for Himawari) There is considerable evolution to the storm during these three hours that present-day GOES cannot view because of limited scanning capabilities. GOES-R will horizontal resolution and scan rates identical to Himawari-8 so meteorologists will be better able to monitor storm evolution.
