Why Typhoons Have Two Names

As 2015 begins, there is another typhoon season approaching in the Philippines. An annual cycle of winds causes most typhoons to develop between May and October. In the northwest Pacific Ocean, two different agencies exist to assign names to typhoons. This often results in the tropical storms having two names, like Haiyan/Yolanda. But why are they so different?

One of the agencies is the Japan Meteorological Agency, or JMA. This agency will only name a typhoon if it has wind speeds of at least 65 km/h (or 40 mph) for at least 10 consecutive minutes. This applies to storms which move into or develop anywhere in the Pacific typhoon basin. Tropical cyclone names are chosen from a set of five lists of names set by the JMA’s Regional Specialized Meteorological Centre in Tokyo once the storm reaches tropical storm strength. Members of the ESCAP/WMO Typhoon Committee contribute the names. Each of the fourteen nations in the Pacific Typhoon Basin submit ten names, which are used in alphabetical order but the official English name of the country. The next tropical storm to be named by the JMA will be Bavi.

The other agency, the Philippine Atmospheric, Geophysical and Astronomical Services Administration, or PAGASA, will assign names to tropical storms which move into or form only in their area of responsibility. This agency will name a typhoon regardless of whether or not it has already been named by JMA, as the agency has its own naming scheme. PAGASA assigns names to tropical depressions from a list of names for the year, in alphabetical order. The next tropical storm to be named by the PAGASA will be Betty.

A tropical cyclone can be labeled any of four divisions, depending on its wind speeds. A Tropical Depression has wind speeds of less than 62 km/h (or less than 39 mph). A Tropical Storm has speeds of between 63 and 88 km/h (or between 39 and 54 mph). A Severe Tropical Storm has wind speeds of between 89 and 117 km/h (or between 55 and 73 mph). A Typhoon is the highest and most dangerous label for a tropical cyclone, having wind speeds of over 118 km/h (or over 74 mph).

Though typhoon season isn’t scheduled to start until May, the Philippines has already been affected by typhoons. In January, a Severe Tropical Storm, named Mekkhala/Amang killed two people and made an airplane crash in Tacloban, although no passengers were killed in the incident. It also disturbed Pope Francis’s visit to the Philippines because of a decision to travel from Tacloban to Manila four hours ahead of the scheduled time.

In February, Typhoon Higos became the strongest February typhoon on record and the easternmost forming Pacific typhoon. Thankfully, it did not cause any significant damage over any islands. Higos was not named by the PAGASA because it did not enter the Philippines’s area of authority.

The Two Seasons

I was curious about the seasons in the Philippines and researched to find that there are really only two official seasons of weather there.

For most of the country the two seasons are:

Dry season (tag-araw)  – November to April

Rainy Season (tag-ulan) – May  to October

However, in some regions the seasons are flipped including Eastern Mindanao, Southern Leyte, Eastern Samar and Southeast Luzon which is rainy from December to March and fairly dry when the rest of the country is soaking wet.

The hottest month is usually May and the coolest least humid months are January and February.

UNICEF Humanitarian Situation Report

Eight months after the typhoon, UNICEF and their partners continue to help try and restore life back to normal for children who have been affected by the disaster. Last month, three villages have had their sanitation practices successfully improved. Humanitarian response and early recovery needs for the children have been fully funded up to November, 2014.

Another Typhoon?

There is yet another strong typhoon that is blowing over the Pacific Ocean in the country’s northeast area and may bring heavy rains, but at this point it is too far off to hit land. However, the disaster response agency has advised villages that have problems with flooding and that are near shore to keep tuned in to the weather, and take precautions. They have also advised fishermen to not go out too far. Let’s hope that if the typhoon does hit the Philippines the people will be more prepared, and no lives will be lost. Everyone keep the Philippines in your prayers and cross your fingers that this typhoon passes right over.
