1.   But the warming of the stratosphere by trapped heat from the sun also changes wind patterns.

2.   Because of the difficulties in predicting wind patterns, it is virtually impossible to guess where the balloon will end up.

3.   A tactical computer will monitor speed, and a polar satellite will provide infrared images of wind patterns and Gulf Stream currents.

4.   But as of Monday evening, the weather in Marrakesh and the high-altitude wind patterns appeared to be just right for takeoff.

5.   But to begin with, they had to set up shop indoors, in a special tank where various wind patterns were simulated.

6.   By using an array of antennae to either create or neutralize ions, they hope to influence local wind patterns and rainfall.

7.   By using an antenna system to either create or neutralize ions, they hope to influence local wind patterns and rainfall.

8.   Changes in Pacific wind patterns and temperatures have caused an upwelling of nutrients from the bottom of the ocean off the coast of Washington and Oregon.

9.   Desert climates result when large-scale wind patterns favor sinking air most of the time.

10.   Factors like wind patterns may influence the exact route.
