Tailend of a Cold Front

A 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. Temperature changes across the boundary can be as much as 50F (30C). When enough moisture is present, rain can occur along the boundary. 

ITCZ

 

ITCZ means Inter-Tropical Convergence Zone. It is a region of convergence between the trade wind systems from the southern and northern hemispheres. Causes thunderstorm convection in tropical regions near the equator.

The position of the ITCZ varies with the seasons. In July, over the Atlantic and Pacific, the ITCZ is between 5 and 15 degrees north of the Equator, but further north over the land masses of Africa and Asia. In January, over the Atlantic, the ITCZ sits no further south than the Equator, but extends much further south over South America, Southern Africa, and towards Australia. Over land, the ITCZ tends to follow the sun's zenith point.

When an aircraft fly through the ITCZ, it  might encounter all the hazards associated with Cb clouds such as icing, turbulence, lightning, and wind shear. However, it is in this zone that the most severe effects may often be encountered.

CLIMATE CHANGE

Climate Change

Global Warming and Climate Change are the same? Well.. not exactly but they are closely related. Global warming causes climates to change. "Global warming" refers to rising global temperatures, while “climate change” includes other more specific kinds of changes, too. Global warming is planet-wide while climate change” can refer to changes at the global, continental, regional and local levels.

Climate Change is a lasting change in the distribution of weather patterns over periods that may lasts for a million years. This is caused the increase in CO2 levels due to emissions from fossil fuel combustion, followed by aerosols and cement manufacture. Other factors, including land use, ozone depletion, animal agriculture and deforestation, are also of concern in the roles they play - both separately and in conjunction with other factors - in affecting the climate. Those things happened because of our wrong way of using our natural resources. We used too much gas that can really harm our beloved Mother Earth. Maybe those disasters’ happening to us now is just the revenge of our Mother Earth to what we have done to her.

Maybe the unpredictable weather that happens to us now is one of its effects. But it’s not yet too late, we can still save our Mother Earth, we can make a better future, a better life and better living. As an individual we can start to ourselves, we can help by just doing simple little things that don’t require a lot of efforts and waste lot money. Planting trees will be a great help and the easiest way. Avoid using too much carbon dioxide in our daily living. Recycling materials. These are just some of the simple ways that can save our nature from harm. Let’s all be hand in hand to save our Earth! We can save MOTHER EARTH :))

El Niño/ La Niña Oscillation

El Niño/La Niña-Southern Oscillation

El Niño/La Niña-Southern Oscillation or also known as ENSO is a quasiperiodic climate pattern that occurs across the tropical Pacific Ocean roughly every five years. It is characterized by variations in the temperature of the surface of the tropical eastern Pacific Ocean. The warming or cooling is known as El Niño and La Niña respectively.
The air surface pressure in the tropical western Pacific is the Southern Oscillation. El Niño is the warm oceanic phase which accompanies high air surface pressure in the Western Pacific. El Niño-Southern Oscillation is often called just "El Niño" which is the Spanish word for "the little boy" that refers to Christ Child which is usually noticed during Christmas Season. It causes extreme weather such as droughts that can destruct our crops.
The cold phase is La Niña which accompanies low air surface pressure in the Western Pacific. La Niña is the name for the cold phase of ENSO, during which the cold pool in the Eastern Pacific intensifies and the trade winds strengthen. The name La Niña originates from Spanish, meaning "the girl". La Niña causes mostly the opposite effects of El Niño. It causes too much floods that might kill our lives and destroy our crops and environment.

MONTREAL PROTOCOL

Montreal Protocol

Due to the too much use of CFCs, our ozone absorbs most of the ultraviolet-B (UV-B) radiation reaching the surface of the planet; depletion of the ozone layer by CFCs would lead to an in increase in UV-B radiation at the surface, resulting in an increase in skin cancer and other impacts such as damage to crops and to marine lifes.

The Montreal Protocol is an international treaty helps to protect the ozone layer by limiting the production of numerous substances believed to be responsible for ozone depletion. The treaty was opened for signature on September 16, 1987, and entered into force on January 1, 1989, followed by a first meeting in Helsinki on May 1989. Since then, it has undergone seven revisions, in London (1990), Nairobi (1991), Copenhagen (1992), Bangkok (1993), Vienna (1995), Montreal (1997), and in Beijing (1999). It is said to be that if the international agreement is adhered, the ozone layer is expected to recover on the year 2050.

The Montreal Protocol has often been called the most successful international environmental agreement to date because there is clear evidence of a decrease in the atmospheric burden of ozone-depleting substances and some early signs of stratospheric ozone recovery like when NASA found out that the thinning at Antarctica had remained the same thickness for the previous three years on year 2001.

Oh MY!! :l

grabe! Supppeerrr Busy ko, rather namin! :(

dami namin kailangan gawin!
lalo na yung sa IP naming lahat, yung sasali sa contest..
need matapos ASAP!

start of something new :)

busy days !!
 
that's why, it's my first time to visit this site..
making blog is fun!!

many paper works to accomplish.
i hate this.. essays.. poems... blah.. blah :p
