Module 7 Flashcards
these are dangers associated with the natural processes or phenomena involved in the transfer of water and energy between the land surface and the lower atmosphere
hydrometerologucal hazards
these are associated with…
typhoons, thunderstorms, flash floods, floods, el nino, la nina, tornadoes and storm surges
these are intense circulating winds with heavy rain over tropical waters and land.
typhoons (118km/hr)
tropical cyclones in the philippines usually begin where?
warm northwestern portion of the pacific ocean
measure of tropical depression
up to 61 kph
measure of tropical storm
62 to 88 kph
measure of severe tropical storm
89 to 117 kph
measure of typhoon
118 to 220 kph
measure of super typhoon
exceeding 220 kph
true or false
typhoons do not weaken when they enter a cooler and drier environment bc they come from warm, moist tropical air
false
this is also known as electrical storm; it is characterized by heavy rain with the presence of thunder and lightning
thunderstorm
this may not have strong winds in contrast with typhoons; there is an uneven distribution of heat in the air and on land
thunderstorm
this can lead to flooding
heavy rainfall
this can electrocute humans and livestock and damge electrial facilities
lightning
this can displace or disorient a flying aircraft
air turbulence
this ca burn buildings and vegetation
fire
this is the presence of excessive water on a supposedly dry land
flood
this is a rapid flow of water on saturated soil or dry soil or any foundation that has a poor absorption capability
flash flood
this usually takes place in volcanoes, mountains, waterways
flash flood
this is an abnormal rise in coastal waters due to a massive force from the sea or from the air above the sea
storm surge
this can be caused by a strong typhoon or sea quake
storm surge
this is a rapidly rotating column of air that is in contact with the air and land
tornado
an average of how many tornadoes can hit the country every year?
12-24
true or false
nueva ecija and bulacan are not prone to tornadoes
false
this refers to the large-scale warming of the ocean and atmosphere across the central and east-central equatorial pacific
el nino
this begins in the eastern part of the pacific ocea, much similar to the location of the other one. ; the ph is affected by excessive rainfall and cold temps
la nina
this is to measure important weather parameters such as the amount of rainfall, direction, speed and intensity of winds
doppler radar
this is usually installed in telecommunication cell sites to observe and locate areas with excessive amount of rainfall; this is to detect possible flooding and flash floods
automated rain gauge
