31. Further down in this section, the 980 millibars can be converted to inches of mercury like this :. 32. Zonal wavenumbers are typically counted on the upper level ( say 500-millibar ) ridges of the waves. 33. The lowest recorded pressure during a hurricane is about 890 millibars , while Luis has hit 940, Rotunno said. 34. This effect is estimated at a increase in sea level for every millibar ( hPa ) drop in atmospheric pressure. 35. At this point in time, Percy was located east of barometric pressure at its center fell to 925 millibars . 36. The left-hand column is depth below sea level in meters, the right hand air pressure in millibars . 37. The strongest of the anticyclones, the one situated over Siberia, registered a maximum high pressure of 1040 millibars . 38. Its also why units such as Angstrom ( for atomic sizes ) and millibar ( for airpressure ) are chosen. 39. The pressure on the Earth is generally close to 1000 millibars , so the pressure on Mars is very low. 40. Where the pressure is 33? millibars , the atmosphere is clear ( probably hydrogen ) and its Rayleigh effect is detectable.
