- Q1What is a tropical cycloneIt is described as a weather disturbance with low pressure characterized by very strong winds blowing counter-clockwise, heavy rainfall and even tornadoesIt is the boundary between two air masses with different temperatureIt is the average weather in a particular place or region over a much longer time frameIt is a large body of air that acquires the physical characteristics mainly temperature and moisture content of the surface of the region over which it is moving.30s
- Q2Where are most Philippine typhoons formed?Caroline-Marianas area of the Pacificat the equatorsea over the Philippine Deepin the northern and southern hemisphere30s
- Q3Weather disturbances usually occur along the boundary betweentwo air masses of different temperaturetwo low pressure areastwo cold frontstwo warm fronts30s
- Q4What two factors cause the winds in a tropical cyclone to spin?cold air rushing toward the eye of the cycloneEarth's rotation and oppsoing directions of the NE and SE Trade Windswarm water and Coriolis effectrising warm air and condensation of its moisture30s
- Q5The properties of an air mass depends onthe temperature and humidity of the land or water over which it is movingthe climate of the regionthe speed and direction of the windits distance from the equator30s
- Q6How would you describe the air mass over the Pacific Ocean on a hot summer day?hot and saltylukewarm and drywarm and moistcold and humid30s
- Q7The changing conditions of the atmosphere result from the interaction of the following excepthumidity of the airwind speedtemperature and pressure of the airlevel of tide waters30s
- Q8For cyclone to continue developing, three conditions are necessary exceptThere must be continuous supply of rising cold airThe air at the center must rise enough to cool and bring about condensationThe exit of the air above is continuous, thus, permitting a continuous flow of warm air from belowThere must be continuously supply of rising warm moist air30s
- Q9Among the factors that contribute to the relatively high incidence of typhoons that visit the Philippines are the following exceptLocation of the Philippines right along the path of typhoons that originate from the Caroline-Marianas areasudden release of energy stores in rockslarge surface area of the pacific ocean and the warm waters of the tropical seapresence of the monsoons particularly the Southwest Monsoon30s
- Q10Trade winds from the Northern and Southern Hemispheres converge at theLPAPARITCZHPA30s
- Q11Weather forecasts are important because we want to know, for instance:if and when the typhoon is expected to enter a leave the PARall of the aboveWhat provinces are on the predicted path of the typhoon and how the typhoon will affect the people's activities and plansif a low pressure area has become a typhoon and how strong it will be30s
- Q12Which of the following is a good effect of typhoons?reduction of air pollutionerosion of steep mountain slopespollution of water with mud/slitfloods/flashfloods30s
- Q13Following is a list of instruments and tools for weather forecasting. Which should be omitted?isobarwind speedaneroid barometeranemometer30s
- Q14An element or factor used in weather forecasting that refers to the amount of water vapor in the air or atmosphere caused by condensation and precipitationwind speedpressurehumidityrainfall30s
- Q15What is the tropical cyclone classification if the wind intensity is greater than 220 kilometers per hour (kph)sever tropical stormtyphoontropical depressionSuper typhoon30s
