WebOct 21, 2024 · High wind shear limits the ability of thunderstorms to organize around the center of the tropical cyclone and intensify the system like it can when the wind shear is low. When the wind shear is moderate, the tropical cyclone may intensify, sometimes rapidly, but may also weaken, making forecasting these systems very challenging. WebA low-level windshear alert system (LLWAS) measures average surface wind speed and direction using a network of remote sensor stations, situated near runways and along approach or departure corridors at an airport.

WebAnother important technology for detecting wind shear is the low-level wind shear alert system (LLWAS). The LLWAS is a ground system that picks up on the presence of wind shear within close range. The weather data is collected and processed by a series of computers that can provide critical warnings to air traffic control towers. WebBy applying the obtained criteria for effective wave coupling to the solar wind parameters, we show that velocity shear- induced linear transformations of Alfvén waves into magneto-acoustic waves could effectively take place for the relatively low-frequency Alfvén waves in the energy containing interval.
