1. The investigation shows that the diverterless supersonic inlet or bump inlet creates a high pressure area on the bump compression surface which pushes the air in boundary layer away from the inlet.

2. In this paper, a detailed analysis is presented for the radial forces of gear pump with expended high pressure area. Some accuracy formulas are given.

3. Warm air is now being drawn in from another high pressure area over the North Sea.

4. The contour map of small circumferential total pressure distortion with high pressure area at centre can be simulated by the method of the combination of lip and rod.

5. All this wet air is pulled in by a high pressure area over the Indian Ocean and a low pressure area to the south.

6. The jet stream is disturbed, and can force a high pressure area to remain longer than it would under normal circumstances.
