Public Storm Signals
3:16:00 am |

~* Today, I learned that Storm Warning Signals are thestorm signals that are usually raised when an area is about to be hit by a tropical cyclone. As a tropical cyclone gains strength and/or gets nearer to an area having a storm signal, the warning may be upgraded to a higher one in that particular area.  Conversely, as a tropical cyclone weakens and/or gets farther to an area, it may be downgraded to a lower signal or may be lifted (that is, an area will have no storm signal). Classes for preschool are canceled when Signal #1 is in effect. High school classes and below are canceled under Signal #2 and classes for colleges and universities and below are canceled under Signal #3.
~*Public Storm Signal No.1*~
Meterological Conditions:
* A tropical cyclone will affect the locality.
* Winds of 30-60 kph may be expected in at least 36 hours or intermittent rains may be expected within 36 hours. (When the tropical cyclone develops very close to the locality a shorter lead time of the occurrence of the winds will be specified in the warning bulletin.) 
Impact of Winds:
* Twigs and branches of small trees may be broken.
* Some banana plants may be tilted or downed.
* Some houses of very light materials (nipa and cogon) may be partially unroofed.
* 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.
* Rice crop, however, may suffer significant damage when it is in its flowering stage.

 ~*Public Storm Signal No.2*~
 Meterological Conditions:
* A tropical cyclone will affect the the locality.
* Winds of greater than 60 kph and up to 100 kph may be expected in at least 24 hours.
Impact of Winds:
 * Some coconut trees may be tilted with few others broken.
* Few big trees may be uprooted.
* Many banana plants may be downed.
* Rice and corn may be adversely affected.
* Large number of nipa and cogon houses may be partially or totally unroofed.
* Some old galvanized iron roofings may be peeled off.
* In general, the winds may bring light to moderate damage to the exposed communities.

 ~*Public Storm Signal No.3*~
Meterological Conditions:
 * A tropical cyclone will affect the locality.
* Winds of greater than 100 kph up to 185 kph may be expected in at least 18 hours.
Impact of Winds:
* Many coconut trees may be broken or destroyed.
* Almost all banana plants may be downed and a large number of trees may be uprooted.
* Rice and corn crops may suffer heavy losses.
* Majority of all nipa and cogon houses may be unroofed or destroyed and there may be considerable damage to structures of light to medium construction.
* There may be widespread disruption of electrical power and communication services.
* In general, moderate to heavy damage may be experienced, particularly in the agricultural and industrial sectors.

 ~*Public Storm Signal No.4*~
 Meterological Conditions:
* A very intense typhoon will affect the locality.
* Very strong winds of more than 185 kph may be expected in at least 12 hours.
Impact of Winds:
* Coconut plantation may suffer extensive damage.
* Many large trees may be uprooted.
* Rice and corn plantation may suffer severe losses.
* Most residential and institutional buildings of mixed construction may be severely damaged.
* Electrical power distribution and communication services may be severely disrupted.
* In the overall, damage to affected communities can be very heavy.
~* I will apply my learning about this in my daily life for the possibility  to raise this storm signal into our area.

 ~* Learning about this phenomenon is important because this lesson can help us to be ready and responsible for any effect of this storm signals.

 ~* On larger scale, I will share my learnings about this phenomenon to my family, my classmates and to any other people for to them to be also ready and knowledgeable of the affect of this phenomenon and for the Precautionary Measures:
* The situation is potentially very destructive to the community.
* All travels and outdoor activities should be cancelled.
* Evacuation to safer shelters should have been completed since it may be too late under this situation.

 ~* I need to know more about this because this information is not enough for me to be ready in this phenomenon.

Parts of a Typhoon
Eye
The centre or eye of a tropical cyclone is at the area of lowest pressure and is characterised by little or no wind and often a cloudless sky. In severe cyclones the eye usually shows up as a circular hole in the central cloud mass. The eye is usually about 40 km in diameter, but can vary between less than 10 km and more than 100 km.

Eye Wall
Surrounding the eye is a wall of dense convective cloud rising about 15 km into the atmosphere. This is the eye wall and is where the most violent winds and heaviest rainfall occur.

Spiral Bands
Radar and satellite observations of tropical cyclones reveal a distinctive pattern of convective cloud bands spiralling into the eye wall. These bands often extend up to 1000 km from the cyclone centre, and contain heavy rain and wind squalls.

Cirrus Canopy
The extremely vigorous uplift of moist air within the convective clouds of the eye wall and inner spiral bands produces a massive outflow of cirrus cloud in the upper atmosphere. This forms a huge canopy over the cyclone, making satellite location of the system centre difficult during the early development stages, before the eye shows through the canopy.
* Today, I learned that a Tropical Cyclone, also called typhoon or hurricane, is intense circular storm that originates over warm tropical oceans and is characterized by low atmospheric pressure, high winds, and heavy rain.It strengthens when water evaporated from the ocean is released as the saturated air rises, resulting in condensation of water vapor contained in the moist air. It generates winds that exceed 119 km (74 miles) per hour.

*  I will apply my learnings about this phenomenon in my daily life wherever am I so I can be alert and aware of the possible things that may happen in our country.

*  Learning about this phenomenon is important because we can be aware all time of the effects of Tropical Cyclone to us.

*  On a larger scale, I  will share my learnings to my classmates, friends, family and to other people for them to be also aware and be ready if this will hit our country, Philippines.

*  I need to know more about the causes and effect of this phenomenon so that I can be responsible of the things am i doing and to be alert of this tropical cyclone whenever it hits us.

La Niña
4:13:00 am |




          Today I learned that LA NIñA is a coupled ocean-atmosphere phenomenon that is the counterpart of El Niño as part of the broader El Niño-Southern Oscillation climate pattern. During a period of La Niña, the sea surface temperature across the equatorial Eastern Central Pacific Ocean will be lower than normal by 3–5 °C. In the United States, an episode of La Niña is defined as a period of at least 5 months of La Niña conditions. The name La Niña originates fromSpanish, meaning "the girl," analogous to El Niño meaning "the boy."
          La Niña, sometimes informally called "anti-El Niño", is the opposite of El Niño, where the latter corresponds instead to a higher sea surface temperature by a deviation of at least 0.5 °C, and its effects are often the reverse of those of El Niño. El Niño is famous due to its potentially catastrophic impact on the weather along both the Chilean, Peruvian, New Zealand, and Australian coasts, among others. It has extensive effects on the weather in North America, even affecting the Atlantic Hurricane Season. La Niña is often, though not always, preceded by an El Niño.

          Today, I learned that EL NIñO is the abnormal warming of surface ocean waters in the eastern tropical Pacific, is one part of what's called the Southern Oscillation (the see-saw pattern of reversing surface air pressure between the eastern and western tropical Pacific). When El Niño conditions last for many months, extensive ocean warming and the reduction in Easterly Trade winds limits upwelling of cold nutrient-rich deep water and its economic impact to local fishing for an international market can be serious.
          I will apply my learning about EL NIñO in my daily activities in life, in at school.
          Learning about EL NIñO is important because I will be more knowledgeable about the warm weather and I'll be ready when it happens.
          On a larger scale, I will share my learnings to other people, students and to my friends &family for them to be also aware and ready if this it will happen and for us to know that this phenomenon will become dangerous and be serious if we will continue on contributing in global warming.
          I need to know more about the causes & effects of EL NIñO so that I will be aware & more responsible in all of the things that I will do and their effects in my environment.

          Today I learned that TROPICAL DEPRESSION is an organized system of clouds and thunderstorms with a defined closed surface circulation and maximum sustained winds of less than 34 knots (39 mph). It has no eye and does not typically have the organization or the spiral shape of more powerful storms.


          I will apply my learnings about TROPICAL DEPRESSION in my daily activities in life.


          Learning about TROPICAL DEPRESSION is important because by gathering facts/infos about it, can help us to be aware of the thins happening around us regarding this phenomenon.


          On a larger scale, I will share my learning about this TROPICAL DEPRESSIONS to other people, student, to my friends and families for them to be also aware and understand this phenomenon and the weather.


          I want to know more about the causes and possible effects of TROPICAL DEPRESSION because it let me understand the weather and the things that are happening in my surroundings.

Entry no.6
July 9-13, 2012


           As a steward of God's creation we should use everything he gave us wisely. 


1.      I conserve water. Turn the faucet off when not in use.
2.      Conserve Electricity. I turn off all appliances that are not in use and I just use it if needed.
3.      I throw my garbages in proper place. In our school we segregate biodegradable from non-biodegradable.

          Today, I learned that COLD FRONT is defined as the leading edge of a cooler mass of air, replacing (at ground level) a warmer mass of air, which lies within a fairly sharp surface trough of low pressure. It forms in the wake of an extratropical cyclone, at the leading edge of its cold air advection pattern, which is also known as the cyclone's dry conveyor belt circulation. It is developed by means of cooler and denser air wedges under the less-dense warm air, lifting it.
          
          The cooler and denser air wedges under the less-dense warmer air, lifting it. This upward motion causes lowered pressure along the cold front and can cause the formation of a narrow line of showers and thunderstorms when enough moisture is present. On weather maps, the surface position of the cold front is marked with the symbol of a blue line of triangles/spikes (pips) pointing in the direction of travel.
              A cold front's location is at the leading edge of the temperature drop off, which in an isotherm analysis would show up as the leading edge of the isotherm gradient, and it normally lies within a sharp surface trough. Cold fronts move faster than warm fronts and can produce sharper changes in weather. Since cold air is denser than warm air, it rapidly replaces the warm air preceding the boundary.:)


             I will apply my learnings about this COLD FRONT in my daily activities,in school (for any lessons regarding this phenomenon),and preparing for any possible outcome of weather problems.


          Learning about this COLD FRONT will help us to become aware, responsible and to understand what are the things that are happening around us.


          On a larger scale, I will share my learnings about this COLD FRONT to other people & students for them to clearly understand and be aware of this phenomenon.


          I want to know more about the causes & effects of COLD FRONT for me to become aware of the thing that may possibly happen around me.
