Across 2. narrow wind band that occurs above large temperature contrasts and can flow as fast as 185 km/hr 3. two global wind systems where air sinks, warms and returns to the equator is a westerly direwction 8. the change that Earth's rotation causes in the motion of objects and that explains that explains how winds curve 10. boundary between two air masses of differing densities 11. global wind systems that are characterized by cold air

Down 1. where surface air moves toward the poles in an easterly direction 4. short-term variations in atmosphere phenomenon that interact and affect the environment and life on Earth 5. area over which an air mass forms 6. large volume of air that has the characteristics of the area over which it forms 7. a long-term average of variations in weather for a particular area 9. cutoff, as in a front where a warm air mass is caught between two cooler air masses
