"Upper-air observations from balloons, from radiosonde instruments attached to balloons, is really one of the best ways we have to get observations," Bradshaw told Wadell.
A hydrogen filled balloon at Cambridge Bay Upper Air station, Nunavut, Canada Launch of wiki payload into stratosphere. Weather balloons are launched around the world for observations used to diagnose current conditions as well as by human forecasters and computer models for weather forecasting.
Upper air observations are the single most important data set driving a forecast model. Fine-scale regional forecast accuracy is dependent on a representation of the mid and upper-level atmospheric flow, moisture, and wave patterns. If these features are properly analyzed during the model initialization period, then an accurate forecast will ensue.
High-quality, spatially and temporally “continuous” data from upper-air monitoring along with surface observations are critical bases for understanding weather conditions and climate trends and providing weather and climate information for the welfare of societies.
The most common station plots depict surface weather observations although upper air plots at various mandatory levels are also frequently depicted. Station model plots use an internationally accepted coding convention that has changed little since August 1, 1941.
An example of a particularly successful step forward in implementing a global observing system for climate is the initiation of a reference network for upper-air observations - the GCOS Reference Upper-Air Network (GRUAN). [16]
The first Weather Bureau radiosonde was launched in Massachusetts in 1937, which prompted a switch from routine aircraft observation to radiosondes within two years. The Bureau prohibited the word "tornado" from being used in any of its weather products out of concern for inciting panic (a move contradicted in its intentions by the high death tolls in past tornado outbreaks due to the lack of ...
Such measurements are performed in a variety of ways including remote sensing and in situ observations. The most common in situ sounding is a radiosonde, which usually is a weather balloon, but can also be a rocketsonde. Remote sensing soundings generally use passive infrared and microwave radiometers: airborne instruments; surface stations
