NOAA/NWS document: wind turbines affect weather radar, create false storm impressions

April 29, 2018 | Anthony Watts | Watts Up With That?
From the Watertown Daily News, and the “law of unintended consequences” department comes an inconvenient truth from the National Weather Service, that upon further investigation appears to be a nationwide problem for the WSR-88D doppler weather radar network used to predict, track, and analyze severe weather. According to NOAA’s Radar operations center, forecasters are faced with “little or no workaround”.
Part of the reason is that the WSR-88D national deployment in the early to mid 1990’s preceded the mass deployment of wind turbines to provide “green energy”. They had no way of knowing then that their field of view would be polluted by an army of rotating blades.

Document from the National Weather Service lists possible radar interference impact from wind turbines

By ABRAHAM KENMORE

WATERTOWN — A new document from the National Weather Service expands on potential interference with the weather radar in Montague, used by personnel at Fort Drum.

In addition to the Buffalo and Burlington, Vt. weather stations which cover Jefferson, Lewis and St. Lawrence counties, the document lists impacts to the Albany and Binghamton National Weather Service stations, which also use the Montague KTYX radar.

Among the possible concerns listed in the document for the Binghamton station is that beam blockage from wind turbines could hamper tracking of thunderstorms in Oneida and Madison counties, delaying tornado warnings. It could also make it difficult to track lake effect snow and rainfall, which in turn could delay travel advice and flash flood warnings.

For the Albany station, the document said that clutter from turbines could create false storm identification and tracking over Lewis and northern Herkimer counties, as well as possibly masking lake effect snow.

The document was sent out by Jessica A. Schultz with the National Oceanic and Atmospheric Administration and lists the possible impact of wind turbines for the four NWS weather stations that use the weather radar. According to documents published online by NOAA, Ms. Schultz works at the NOAA NWS Radar Operations Center in Oklahoma. Although the document itself is unsigned, the document’s properties list the author as being a JSchultz.
