This composite image shows typhoon Violet, along with
surrounding winds measured by NSCAT, near Japan on September 20,
1996. The NSCAT data on surface wind direction and speed (wind
vectors) are superposed atop an infrared cloud image from the
Japanese meteorological satellite GMS-5. Wind direction is shown
by arrows; here again, blue represents low wind speeds and red
high ones. An apparent drop in wind speed near the center of the
storm is probably due to attenuation of the satellite's radar
signal by rain. This image is typical of the data that will be
generated using NSCAT and made available to meteorologists.

It’s Time to Stand Up for Science

If you enjoyed this article, I’d like to ask for your support. Scientific American has served as an advocate for science and industry for 180 years, and right now may be the most critical moment in that two-century history.

I’ve been a Scientific American subscriber since I was 12 years old, and it helped shape the way I look at the world. SciAm always educates and delights me, and inspires a sense of awe for our vast, beautiful universe. I hope it does that for you, too.

If you subscribe to Scientific American, you help ensure that our coverage is centered on meaningful research and discovery; that we have the resources to report on the decisions that threaten labs across the U.S.; and that we support both budding and working scientists at a time when the value of science itself too often goes unrecognized.

In return, you get essential news, captivating podcasts, brilliant infographics, can't-miss newsletters, must-watch videos, challenging games, and the science world's best writing and reporting. You can even gift someone a subscription.

There has never been a more important time for us to stand up and show why science matters. I hope you’ll support us in that mission.

Thank you,

David M. Ewalt, Editor in Chief, Scientific American
