Monsoon

MONSOON

Monsoon - a wind from the Southwest or South that brings heavy rainfall to Southern Asia in the summer.

                - sometimes primarily by much greater annual variation in temperature over large areas of land the          large areas of adjacent ocean water.

                - traditionally defined as a seasonal reversing wind accompanied by corresponding changes in precipitation.

Monsoon Rain - is a geographical phenomenon caused by cyclic air movements changing with the time of a   year.

Types of Monsoons

Summer Monsoon/Southwest Monsoon - takes place in the form of cycles with the cool air of the oceans blowing towards the land and creating precipitation and releasing energy. The ITCZ shifts northwards as the sun is overhead at the tropic of cancer. Equitorial Maritime air is drawn north and diverted northeast due to the coriolis force. The humid unstable air results in rainfall.

                   - the southwest monsoon/s prevails during May to October. The wind in Australia flows from Southeast direction going to the equator.

Winter Monsoon/Northeast Monsoon - in winter, when the land mass of the continents is cold and the water is warmer, the air flows in the reverse direction. Low temperature over Central Asia create areas of high pressure, at the same time, the subtropical jet and ITCZ shift south. Air moving out from the area of high pressure is very dry and becomes drier as it crosses over the Himalayas, causing clear skies and sunny weather over most India from November to May.

The Effects of Monsoon

Drought - The countries affected by monsoon season welcome the rain as a point at which drought ends. However, if the rainfall in this season is below average then further drought can be devastating. This leads to food supplies dwindling and crops unable to grow, and many of the area's inhabitants may die of famine.

Floods -  Those who make their living from the land welcome the season, where the rains will make a large contribution to the crops they produce. However, when too much rain comes in a short period of time this can cause flash floods that not only damage crops and drown livestock, but also harm inhabitants of the area. However, in less extreme forms these floods help to fertilise the soil.
Agriculture and Economy - The patterns of the monsoon have a huge impact on farmers and their crops and livestock. If the rains don't come as expected then farming patterns can be disrupted.

Coriolis Effect

                    Coriolis effect is an inertial force described by the 19th-century French engineer-mathematician Gustave-Gaspard Coriolis in 1835. Coriolis showed that, if the ordinary Newtonian laws of motion of bodies are to be used in a rotating frame of reference, an inertial force--acting to the right of the direction of body motion for counterclockwise rotation of the reference frame or to the left for clockwise rotation--must be included in the equations of motion.


                     The effect of the Coriolis force is an apparent deflection of the path of an object that moves within a rotating coordinate system. The object does not actually deviate from its path, but it appears to do so because of the motion of the coordinate system.


                      The Coriolis effect is most apparent in the path of an object moving longitudinally. On the Earth an object that moves along a north-south path, or longitudinal line, will undergo apparent deflection to the right in the Northern Hemisphere and to the left in the Southern Hemisphere. There are two reasons for this phenomenon: first, the Earth rotates eastward; and second, the tangential velocity of a point on the Earth is a function of latitude (the velocity is essentially zero at the poles and it attains a maximum value at the Equator). Thus, if a cannon were fired northward from a point on the Equator, the projectile would land to the east of its due north path. This variation would occur because the projectile was moving eastward faster at the Equator than was its target farther north. Similarly, if the weapon were fired toward the Equator from the North Pole, the projectile would again land to the right of its true path. In this case, the target area would have moved eastward before the shell reached it because of its greater eastward velocity. An exactly similar displacement occurs if the projectile is fired in any direction.

1. TODAY I LEARNED THAT  monsoon is a wind from the Southwest or South that brings heavy rainfall to Southern Asia in the summer.
2. I WILL APPLY MY LEARNINGS ABOUT monsoon, just like what I did to the last topic and will be doing more in the future, will apply my knowledge in my everyday life.
3. LEARNING ABOUT THIS TOPIC IS IMPORTANT BECAUSE as people, we would want to be alert about everything that is going on anywhere not to be "in" , as others wil say, but to be able to share more and let others become AWARE about everything that is going on or will happen.
4. ON A LARGER SCALE, I WILL SHARE MY LEARNINGS ABOUT THIS PHENOMENON TO OTHERS BECAUSE as I said in the previous number, I would really be happy to let others become AWARE about everything that is going on or will happen in their lives. After al,, we are humans. We should care about others too.
5. I NEED TO KNOW MORE ABOUT a lot of things about this topic. Researchs will be done over and over agaain. I will, of couse, want to know about the new informations on this topic in the near future. But for now, this important information will keep me satisfied. =D
