Have you ever taken off in an aircraft and wondered why you were heading in the opposite direction? Find out why here
By noting the sideways movement of the ascending balloon, they can calculate wind speed and wind direction at different altitudes. There's a reason weather balloons don't just float into space. As the balloon moves farther away from Earth, there's less air to push against the outside of ...
century later. Scientists had by then determined that acid rain was a transboundary rather than a local concern. In 1980, the Acid Deposition Act launched a 10-year study on acid rain under the direction of theNational Acidic Precipitation Assessment Program (NAPAP)to monitor sites around the ...
Wind Direction and Speed There are two options for describing wind speed and direction: Onshore winds: These winds blow from the ocean to the shore. Offshore winds: Offshore winds blow from the shore to the ocean. Offshore winds create better surfing conditions because they blow against th...
Radar systems can detect wind speed and direction, so we can prepare better for severe weather. Precipitation gives us these weather pictures. Radar processing systems convert returned signal strength to precipitation intensity with advanced algorithms. How?
Clouds can tell you what the wind is doing in the upper parts of the atmosphere, and they show what direction the weather is coming from. Clouds can also reveal how stable or unstable the atmosphere is and how far away a storm may be. ...
THE NEXUSES BETWEEN WIND AND RAINFALL PATTERNS: USING WIND TO PREDICT RAINFALL FOR ENHANCED ADAPTABILITY TO RAINFALL RELATED HAZARDS It was found that wind tended to blow from the east most of the time and from the south during the long rainy season. Farmers can use the direction... SN Lusi...
One of these models is called RAFT—Risk Analysis Framework for Tropical Cyclones—and contains 40,000 simulated tropical cyclones created by incorporating historical records. Researchers can use RAFT to simulate wind speed, rainfall and direction of travel to aid with disaster planning. ...
Feel the direction of the wind. A wind blowing from the east shows that a storm will probably happen. A wind from the west means a sunny day. Look at the clouds. There are three things about clouds you should pay attention to: movement, color, and change. As a rule, the higher the...
Bz is the solar wind's magnetic orientation in the up/down direction. Although an Aurora can happen with a positive Bz, a negative Bz is generally better. A negative Bz helps the solar wind grab the earth's magnetic field which can more easily lead to an Aurora. So a negative Bz is ...
