28
Q

From Indian word mawsim meaning seasons
Seasonally changing winds caused by connection currents that bring additional rain or dry cold air depending on where they come from

A

Monsoon

29
Q

Known as Hanging habagat
convection current brings humid air from Indian Ocean and moves from south west
June to October

A

Southwest monsoon

30
Q

Hanging amihan; convection currents coming from Siberia and China that blows cool air over the entire South East Asian region
November to may

A

North-east monsoon

31
Q

Winds that blow from a single direction over a specific area of earth

A

Prevailing surface winds

32
Q

What does ITCZ mean?

A

Intertropical convergence zone

33
Q

Belt of low pressure which circles the earth generally near the equator where the Tradewinds of the northern and southern hemispheres come together

A

Intertropical convergence zone

34
Q

Amount of hours of daylight is a part of earth that is dictated by two factors

A

Earth’s orbit

35
Q

Earth is farthest from the sun
Happens in July

A

Aphelion

36
Q

Earth is closest to the sun
Happens during December or January

A

Perihelion

37
Q

Same hours of the day and night

A

Equinox

38
Q

Longest or shortest hours of daylight

A

Solstice

39
Q

Earth axial tilt is about 23.5° this causes the seasons

A

Tilt of the Earth

40
Q

0 to 23.5°, In the regions between the equator and the tropics (equatorial region), the solar radiation reaches the ground nearly vertically at noontime during almost the entire year. Thereby, it is very warm in these regions

A

Tropical zone

41
Q

23.5°–40°
receive the highest radiation in summer, since the Sun’s angle at noon is almost vertical to the Earth, whilst the cloud cover is relatively thin

A

Subtropics

42
Q

40°–60°
the solar radiation arrives with a smaller angle, and the average temperatures here are much cooler than in the subtropics. The seasons and day length differ significantly in the course of a year

A

Temperate zone

43
Q

60°–90°
The polar areas between 60° latitude and the poles receive less heat through solar radiation, since the Sun has a very flat angle toward the ground

A

Cold zone

44
Q

Average weather of a locality over a period of time

A

Climate

45
Q

Daily overall atmospheric conditions in an area

A

Weather

46
Q

The characteristic weather patterns for that particular length of time

A

Seasons

47
Q

What is PAGASA

A

Philippine atmospheric geophysical and astronomical services Administration they are responsible for weather and temperature forecasts

48
Q

(June and October)
The atmosphere and the amount of solar radiation are two of these factors that play a big role.

A

Rainy season

49
Q

are localized atmospheric phenomena made up of hundred of storm clouds that form over the oceans and bring with them heavy rains and strong winds

A

Tropical cyclones

50
Q

caused by northeast monsoon, which can start from late October and end in early March

A

Cold dry season

51
Q

coincides with the time the seasonal winds are transitioning between the cool dry season and the rainy season

A

Warm dry season

52
Q

overall weakness you would feel because of overheating

A

Heat exhaustion

53
Q

cramps that happen after excessive sweating

A

Heat cramps

54
Q

most severe of the heat-related illnesses, which can happen when the body reaches a temperature of 40 degrees Celsius

A

Heat stroke

55
Q

Formed when an object obstructs the path of light

A

Shadow

56
Q

Darkest part of a shadow where light is completely blocked

A

Umbra

57
Q

A lighter shadow surrounded by a darker region, is observed during certain conditions like solar eclipses

A

Antumbra

58
Q

can be seen as the partially shaded area surrounding the umbra

A

Penumbra

59
Q

Occurs when one celestial body passes through the shadow of another celestial body

A

Eclipse

60
Q

occurs when the Moon passes between the Sun and Earth, blocking or partially blocking the Sun’s light. This can result in a partial or total obscuration of the Sun as seen from Earth

A

Solar eclipse

61
Q

takes place when Earth comes between the Sun and the Moon, causing Earth’s shadow to be cast on the lunar surface. This results in a darkening or reddening of the Moon

A

Lunar eclipse

62
Q

Moon partially covers the sun casting only a portion of its shadow on earth

A

Partial solar EclipsE

63
Q

happens when the Moon passes between the Sun and Earth, but when it is at or near its farthest point from Earth

A

Annular solar eclipse

64
Q

Moon completely covers the sun, blocking its entire disk

A

Total solar eclipse

65
Q

Portion of moon moves into the earth’s umbra

A

Partial lunar eclipse

66
Q

Entire moon moves into earths umbra

A

Total lunar eclipse

67
Q

The moon passes through the earth’s penumbra

A

Penumbral lunar eclipse
