Meteorologist Dr. Ryan Maue demolishes claims that Typhoon Haiyan was «strongest storm ever» — «Fact: Haiyan is 58th Super Typhoon since 1950 to reach central pressure of 900 mb or lower from historical records» — Maue: ’50 of 58 Super Typhoons with pressure of 900 mb or lower occurred from 1950 - 1987 — only 8 in past 25 years»

Summer cyclones and anticyclones exhibit little regional variability in mean central pressure, and are typically 5 — 10 mb weaker than their winter counterparts.

As reported in the SAR, a part of the multi-decadal trend of tropical cyclones occurring in the Australian region (105 ° to 160 ° E) is likely to be artificial, as the forecasters in the region no longer classify some weak (> 990 hPa central pressure) systems as cyclones (Nicholls et al., 1998).

The estimated minimum central pressure is 981 millibars.

Previous work has observed that central pressure deficit depends on maximum wind speed, storm size, and latitude, but Chavas» team has determined why that is.

«If you looked at the central pressure deficit, you would have expected it to cause a lot of damage.

The Purdue team's work shows that central pressure deficit itself may achieve this goal, or at least do a better job than maximum wind speed alone.

As we have discussed elsewhere on this site, statistical measures that focus on trends in the strongest category storms, maximum hurricane winds, and changes in minimum central pressures, suggest a systematic increase in the intensities of those storms that form.

With a central pressure forecast to drop very low (see plot below), the storm will threaten the record set by unprecedented 2012 Superstorm Sandy as the lowest surface pressure ever measured in the North Atlantic north of Cape Hatteras (the central surface pressure of a storm is one measure of its strength).

As I write this, Hurricane Sandy's minimum central pressure has dropped to a stunning 940 millibars, meaning that air is rising in this storm in a way similar to a Category 4 hurricane.

Thus to sustain a given pressure gradient and thus the winds, the central pressure must accordingly be smaller in this basin.)

The Minimum Central Pressure, being 879 millibars, was off the charts, then for the hurricane to move in, over Western Mexico is somewhat uncommon, as the majority of storms steering patterns move the systems westerly out over the open ocean.

However, since the winds are really determined by the pressure gradient, small tropical cyclones (like the Atlantic's Andrew in 1992, for example) can have stronger winds for a given central pressure than a larger tropical cyclone with the same central pressure.
