Storm Signals

1. I learned that an area is under storm signal no. 1 when winds of 30-60 kph may be expected in at least 36 hours. Signal no. 2 when winds of greater than 100 kph up to 185 kph may be expected in at least 18 hours. Signal no. 3 winds of greater than 60 kph and up to 100 kph may be expected in at least 24 hours. Very strong winds are coming generally from the north. signal no. 4 when very strong winds of more than 185 kph may be expected in at least 12 hours. With storm signal no. 4, the locality is very likely to be hit directly by the eye of the typhoon. As the eye of the typhoon approaches, the weather will continuously worsen with the winds increasing to its strongest coming generally from the north. Then a sudden improvement of the weather with light winds (a lull) will be experienced.
2. I want to know more about the formation of a typhoon and the factors that affect the signal no. of an area.
3. I would like to research on the different precautionary measures that I can be used when our area is experiencing typhoon of any signal no.
4. I appreciate the fact that there is a weather agency in the Philippines (PAGASA) that informs the countrymen when there is a storm forming near the country and announces the areas that are under the storm signal nos.
5. I can apply my learning and insights in understanding the weather condition of our country esp. when we are experiencing typhoon.

Storm Signal No. 4

1. I learned that an area is under storm signal no. 4 when very strong winds of more than 185 kph may be expected in at least 12 hours. With storm signal no. 4, the locality is very likely to be hit directly by the eye of the typhoon. As the eye of the typhoon approaches, the weather will continuously worsen with the winds increasing to its strongest coming generally from the north. Then a sudden improvement of the weather with light winds (a lull) will be experienced. This means that the eye of the typhoon is over the locality. This improved weather may last for one to two hours depending on the diameter of the eye and the speed of movement. As the eye moves out of the locality, the worst weather experienced before the lull will suddenly commence. This time the very strong winds will come generally from the south.
2. I want to know more how a storm signal no. 3 turns into signal no. 4 and its effect on the country.
3. I would like to research on the different precautionary measures that I can be used when our area is under such worst condition.
4. I appreciate the fact that there is a weather agency in the Philippines (PAGASA) that informs the countrymen when there is a storm forming near the country and announces the areas that are under the storm signal no. 4.
5. I can apply my learning and insights in understanding the weather condition of our country esp. when we are experiencing storm signal no. 4.

Storm Signal No. 2

1. I learned that an area is under storm signal no. 2 when winds of greater than 100 kph up to 185 kph may be expected in at least 18 hours.
2. I want to know more how a storm signal no. 1 turns into signal no. 2 and its effect on the country.
3. I would like to research on the different precautionary measures that I can be used when our area is under storm signal no. 2.
4. I appreciate the fact that there is a weather agency in the Philippines (PAGASA) that informs the countrymen when there is a storm forming near the country and announces the areas that are under the storm signal no. 2.
5. I can apply my learning and insights in understanding the weather condition of our country esp. when we are experiencing storm signal no. 2.

Storm Signal No. 3

1. I learned that an area is under storm signal no. 3 when winds of greater than 60 kph and up to 100 kph may be expected in at least 24 hours. People should watch out for the passage of the "eye" of the typhoon indicated by a sudden occurrence of fair weather immediately after very bad weather with very strong winds coming generally from the north.
2. I want to know more how a storm signal no. 2 turns into signal no. 3 and its effect on the country.
3. I would like to research on the different precautionary measures that I can be used when our area is under storm signal no. 3.
4. I appreciate the fact that there is a weather agency in the Philippines (PAGASA) that informs the countrymen when there is a storm forming near the country and announces the areas that are under the storm signal no. 3.
5. I can apply my learning and insights in understanding the weather condition of our country esp. when we are experiencing storm signal no. 3.

Storm Signal No. 1

1. I learned that an area is under storm signal no. 1 when winds of 30-60 kph may be expected in at least 36 hours or intermittent rains may be expected within 36 hours.
2. I want to know more about the causes and effects of storm signal no. 1.
3. I would like to research on the different precautionary measures that I can be used when our area is under storm signal no. 1.
4. I appreciate the fact that there is a weather agency in the Philippines (PAGASA) that informs the countrymen when there is a storm forming near the country and announces the areas that are under the storm signal no. 1.
5. I can apply my learning and insights in understanding the weather condition of our country esp. when we are experiencing storm signal no. 1.

Fujiwhara Effect

1. I learned that Fujiwhara Effect is a binary interaction where tropical cyclones within a certain distance (300-750 nautical miles depending on the sizes of the cyclones) of each other begin to rotate about a common midpoint. In 1921, a Japanese meteorologist named Dr. Sakuhei Fujiwhara determined that two storms will sometimes move around a common center pivot point.

2. I want to know more about the formation of the said phenomenon.

3. I would like to research on the different effects of the Fujiwhara Effect in the weather of the country and the different weather  instruments that can be used to detect the incoming of such phenomenon.

4. I appreciate the fact that there are meteorologist and weather agencies that are willing to study about the mentioned phenomenon so that if such would get into the country, people will be informed.

5. I can apply my learning and insights in understanding the weather of the country esp. if there will be a Fujiwhara Effect that will form in the country.

Tail-end of Cold Front

1. I learned that the Tail-end of a Cold Front is a front boundary of 2 air masses, which is found in a middle latitude. It causes too much rainfall and cloudiness over affected areas and usually occurs on the Northern portion of the country during the Northern Hemisphere in a winter season. It is defined wherein the cooler mass of air used to replace the warmer mass of air, which results to a lower pressure in that surface. It is a phenomenon wherein it can experience a change in a temperature.

2. I want to know more about the formation of tail-end of a cold front; how it forms and what are the factors that affects its formation.

3.  I would like to research on its relation on the different phenomena of the country such as typhoon, tropical depression, etc., and if it affects the condition of the mentioned phenomena. Moreover, I would like to know about how PAGASA detects if there is a tail-end of cold front forming in our country and what weather instruments they are using for detecting.

4. I appreciate the fact that I gain a knowledge about an important weather-related system on our country.

5. I can apply me learning and insights in understanding the weather of our country.
