Of course, now that you have more than one target selected you are not able to adjust the range to the target as you did earlier, as scrolling left and right now changes the selected target, not the range. The disputed absolute highest wind speed ever recorded on earth was during the Bridge Creek-Moore tornado in Oklahoma (USA) in 1999. The measurement was from a doppler radar anemometer. Although exact wind speeds are up for debate, the wind speed probably surpassed 490km/h (305mph).

Perceived temperature resulting from the combined effect of temperature and relative humidity. Calculated based on NWS Heat Index (HI) tables. Measurement range limited by extent of published tables All Kestrel models can be fitted to a portable rotating wind vane mount and tripod, to create a very portable and accurate weather station.

Anemometers can accurately monitor the wind speed and provide the data for the measurements in various ways. There are several types of anemometers and each one functions differently depending on what type it is and what type of wind measurement application it is used for. Most handheld wind speed monitors are rugged and durable to withstand the elements that they may be presented with, as well as being weatherproof, especially those that can be mounted to measure over long periods of time. They are used in a variety of applications from weather predictions to high-tech scientific research labs. Types of Anemometer inch|25 mm diameter impeller with precision axle and low-friction Zytel® bearings. Startup speed stated as lower limit, readings may be taken down to 0.4 m/s |79 ft min|1.5 km/h |.9 mph |.8 kt after impeller startup. Off-axis accuracy -1% @ 5º off axis; -2% @ 10º; -3% @ 15º. Calibration drift < 1% after 100 hours use at 16 MPH|7 m/s. Replacement impeller (NK PN-0801) field installs without tools (US Patent 5,783,753). Wind speed calibration and testing should be done with triangle on impeller located at the top front face of the Kestrel. Measuring wind speeds above 60 m/s / 134.2 mph can damage the impeller On occasion, you are going to notice that the first wind measurement is saying something like ‘.068L’, yet the wind reading is saying ‘3.76R’. You know the wind is coming from the right, so why is the Kestrel saying to aim off to the left as the lowest wind reading? The simple answer to this one is spin drift. If you have no wind to affect the bullet you will still need to hold off to the left to counter the spin drift. Your Kestrel can be set to calculate and thus compensate for spin drift. Spin drift is turned on by default. It can be turned off via the Environment menu. The word anemometer actually originated from the Greek word “anemos”, which translates to “wind”. Nowadays anemometer is still the most commonly used term for referring to a wind speed measuring tool, especially in the scientific field.Calculates relative humidity, heat stress index, wind chill, dew point temperature wind speed and more Paragliders and glider aeroplanes use the data from the anemometer to ensure conditions are safe to fly The wind speed displayed is a 3 second rolling average. This allows the unit to provide a value that is more representative of the typical, ambient conditions rather than peak speeds for instantaneous blasts of air.
