94.   Speed will be governed by an air cleaner that has been changed to limit air flow, thus hampering engine performance.

95.   Stacking the cells restricts air flow and creates the need for an air pump.

96.   Stack the wood to promote air flow.

97.   Streamers of cirrus clouds will streak the sky over parts of the Rockies as moist Pacific air flows over the mountains.
