Typhoon Haiyan: how does it compare with other tropical cyclones?
Typhoon Haiyan, described as the as the strongest tropical cyclone to make landfall in recorded history, hit the Philippines with winds of 195mph. How does it compare with other tropical cyclones?
Hitting the Philippines with winds of 195mph, typhoon Haiyan has been described as the strongest tropical cyclone to make landfall in recorded history.

The category fivestorm - which has also been called Yolanda in the Philippines - is reported to have had speeds at landfall of 195mph and gusts of up to 235mph, meaning that it is believed to be stronger than the world's last strongest tropical cyclone, hurricane Camille, which was recorded as making landfall in Mississippi with 190 mph winds in 1969.

The Guardian's south-east Asia correspondent, Kate Hodal, writes today :


Typhoon, hurricane or cyclone?

If the usage of the terms hurricane, typhoon and cyclone are getting you in a bit of a mix, don't worry. According to the National Oceanic and Atmospheric Administration (NOAA) these are simply different names for the same weather phenomenon. The term 'hurricane' is used in the Atlantic and Northeast Pacific, 'typhoon' is used in the Northwest Pacific and 'cyclones' are the term to use in the South Pacific and Indian Ocean.

You might also have seen Haiyan referred to as a super-typhoon. The Nooa can also clear this one up, according to the definition on their website a super-typhoon is


The Noaa also explain that there are several ways in which a tropical cyclone's intensity can be measured; either central pressure or highest measured wind speed. But measuring such high winds can be tricky as the Noaa note "measurements of such winds are inherently going to be suspect as instruments often are completely destroyed or damaged at these speeds."

How does typhoon Haiyan compare?
Dr Jeff Masters, meteorologist and co-founder of the Weather Underground has attempted to answer just this question. Haiyan which came ashore at 4:40 am local time has been reported as making landfall at 195mph. Masters explains how the reported wind speed has been calculated:



As Masters explains, Haiyan although the strongest tropical cyclone on record to make landfall in world history, it is actually the fourth strongest tropical cyclone in history. We've put the list of official strongest cyclones in world history that Master cites into the table below:



An important thing to note though is that the Noaa have stated that the maximum sustained winds estimated for typhoons during the 1940s to 1960s were too strong.

The image was taken on November 7th at 8am Eastern Standard Time by the Japan Meteorological Agency and EUMETSAT (the European Organisation for the Exploitation of Meteorological Satellites)


Satellite images show the extent of the storm as it approached the Philippines on 7 November. At times it stretched 600km (372 miles) across.

ternyata jadi HT ya....
sori... lupa comment

semoga sodara2 kita di Filipina dapat melalui musibah ini dan bangkit kembali.
