| Today, a bomb cyclone is an extratropical area of low pressure in which the central barometric pressure drops at least 24 millibars in 24 hours. |
| According to the model, barometric pressure in the lowest stratum rose by 145 millibars to 1,108 millibars. |
| Average barometric pressure in Tampa Bay during the summer is about 29.8 inches of mercury or about 1013 millibar. |
| Of even more importance to freshwater fishing, and particularly dams or impoundments, is the barometric pressure. |
| In our hemisphere, areas of high barometric pressure, anticyclones, create winds which circulate anticlockwise. |
| The turtle recorded a barometric pressure drop of 100 millibars within the vortex. |
