71.   That allows weather forecasters to use radar to determine wind speed and direction, not just the location and intensity of precipitation.

72.   The beaker lost heat faster, of course, the lower the air temperature and the higher the wind speed.

73.   The attackers damaged a device that monitors the wind speed and direction and sends the information back to a central computer.

74.   The agency confirmed that weather conditions and wind speeds and directions could have accounted for the odors being driven north and inland.

75.   The airport does have a less-sophisticated, low-level wind-shear alert system with sensors that measure wind speed and direction.

76.   The change in wind speed with height, called wind shear, creates the twisting motions that can lead to tornado formation.

77.   The difference in wind speed causes air to spin around a horizontal axis.

78.   The cups are connected to a gauge with a red needle that shows wind speed in miles per hour and knots.

79.   The flood of solar energy sets the air in motion causing wind speed to increase.

80.   The flood of solar energy sets the air in motion, causing wind speed to increase.
