NASA Earth Observatory’s November 3, 2026, feature examines late-October storm activity across the Pacific. An October 29 image from the DSCOVR satellite’s EPIC instrument places Super Typhoon In-fa and the remnants of Typhoon Champi in a wider view of the Northern Hemisphere. A second image, captured by Terra’s MODIS instrument on October 30, shows In-fa’s pronounced eye.
One event, more than one perspective
The feature describes how a tropical system and an evolving extratropical system can appear in the same regional picture while drawing energy from different conditions. It connects Champi’s remnants with a larger system approaching Alaska. The imagery documents those historical observations; it is not a live forecast or a new warning for the places shown.
The contrast between the broad image and the closer storm view is useful in its own right. One helps a reader follow relationships across a large area. The other reveals the structure of a particular system. Neither perspective alone answers every question an observer might ask.
What this means for data products
Our analysis is that the feature offers a practical lesson for organizations building visual decision tools: choose the scale according to the decision. A dashboard can reveal a local anomaly while concealing the wider process that explains it. An overview can show connections while leaving out details needed to investigate one location.
A useful interface makes it easy to move between those levels without losing the timestamp, instrument and meaning of the observation. It should also distinguish measured information from interpretation and prediction. A persuasive image becomes more informative when readers can understand how it was produced.
For operational weather decisions, current information should come from the relevant meteorological authorities. The value of this published satellite record is explanatory: it allows a complex regional situation to be examined with a clear account of where and when the observations were made.
