Storm Signal

I learned that there are different storm signals depending upon the strength of the cyclone. Public storm signal #1 exhibits winds of 30-60 kph that may be expected in at least 36 hours or intermittent rains may be expected within 36 hours. Unless this warning signal is upgraded during the entire existence of the tropical cyclone, only very light or no damage at all may be sustained by the exposed communities. Public storm signal #2 exhibits winds of greater than 60 kph and up to 100 kph that may be expected in at least 24 hours. In general, the winds may bring light to moderate damage to the exposed communities. Public storm signal #3 exhibits winds of greater than 100 kph up to 185 kph that may be expected in at least 18 hours. In general, moderate to heavy damage may be experienced, particularly in the agricultural and industrial sectors. I want to know more about the different instruments used to detect the strength of the cyclone. I would like to research on how to easily detect the coming of a cyclone. I appreciate the fact that Philippines has now instruments to help determine natural calamities such as cyclones. I can apply my learning and insights in my daily life, that when there’s a cyclone I have enough knowledge to do the necessary things to lessen the damage that it may cause. 

Fujiwhara Effect

I learned that Fujiwhara effect or Fujiwara interaction, named after Sakuhei Fujiwhara, is a type of interaction between two nearby cyclonic vortices, causing them to appear to "orbit" each other. When the cyclones approach each other, their centers will begin orbiting cyclonically about a point between the two systems due to their cyclonic wind circulations. The two vortices will be attracted to each other, and eventually spiral into the center point and merge. When the two vortices are of unequal size, the larger vortex will tend to dominate the interaction, and the smaller vortex will orbit around it. The effect is often mentioned in relation to the motion of tropical cyclones, although the final merging of the two storms is uncommon. The effect becomes pronounced in these storms when they approach within about 1,500 km (900 mi) of each other and are at tropical storm strength or stronger. The effect is named after Sakuhei Fujiwhara, the Japanese meteorologist who initially described it in a 1921 paper about the motion of vortices in water. I want to know more about on how this interaction takes place and what causes it to take place. I would like to research on how it can affect the strength of cyclones and how it can be determined easily. I appreciate the fact we are now knowledgeable about this kind of phenomenon. I can apply my learning and insights in my everyday life, if there is an occurence of such phenomenon i'll be knowledgeable about the things to be done.

Tropical Cyclone

I learned that a tropical cyclone is a storm system characterized by a low-pressure center and numerous thunderstorms that produce strong winds and heavy rain. Tropical cyclones strengthen when water evaporated from the ocean is released as the saturated air rises, resulting in condensation of water vapor contained in the moist air. They are fueled by a different heat mechanism than other cyclonic windstorms such as nor'easters, European windstorms, and polar lows. The characteristic that separates tropical cyclones from other cyclonic systems is that at any height in the atmosphere, the center of a tropical cyclone will be warmer than its surroundings; a phenomenon called "warm core" storm systems. The term "tropical" refers both to the geographical origin of these systems, which usually form in tropical regions of the globe, and to their formation in maritime tropical air masses. The term "cyclone" refers to such storms' cyclonic nature, with counterclockwise wind flow in the Northern Hemisphere and clockwise wind flow in the Southern Hemisphere. The opposite direction of the wind flow is a result of the Coriolis force. Depending on its location and strength, a tropical cyclone is referred to by names such hurricane, typhoon, tropical depression, cyclonic storm, and simply cyclone. I want to know more about the development of tropical cyclones as they pass through a certain place. I would like to research on how we can have the accurate prediction about tropical cyclones. I appreciate the fact that there are instruments we can use to help us determine the necessary information about the tropical cyclone. I can apply my learning and insights in being ready for tropical cyclones that may hit our country, this will help lessen the damage tropical cyclones can brought to us.
