Anemometer have accurate wind data under all conditions, including freezing precipitation. Anemometry is also required in monitoring and controlling the operation of wind turbines, which in cold environments are prone to in-cloud icing. Icing alters the aerodynamics of an anemometer and may entirely block it from operating. Therefore, anemometers used in these applications must be internally heated. Both cup anemometers and sonic anemometers are presently available with heated versions. In order for wind speeds to be comparable from location to location, the effect of the terrain needs to be considered, especially in regard to height. Other considerations are the presence of
What Kate Does doesn't quite know how to write a woman of action who's also in love … many of the show's Kate flashbacks are just plain silly … there have been a lot of pretty dire Kate episodes." Whitney Matheson of "USA Today" said that she "wanted to stab Kate with a hot poker" after watching "What Kate Does".
