Q: What is the diurnal range of temperature?
A: The diurnal range of temperature is the difference between the maximum and minimum temperatures of a day.
Q: What are isotherms?
A: Isotherms are imaginary lines which connect places with the same temperatures on a map.
Q: Why does the Polar region experience extreme cold winters?
A: The Polar region receives slanting sun’s rays, resulting in little or no sunlight and extremely cold temperatures.
Q: What is insolation?
A: Insolation refers to the solar radiation that reaches the Earth’s surface.
Q: What is the dew point?
A: The dew point is the temperature at which the air becomes saturated and water vapor begins to condense.
Q: What are the three mechanisms through which the Earth receives heat energy from solar radiation?
A: The three mechanisms are radiation, conduction, and convection.
Q: What is the significance of the 100% relative humidity?
A: When relative humidity reaches 100%, the air is saturated and further cooling will condense water vapor into clouds and rain.
Q: What is a meteorograph?
A: A meteorograph, also known as a triple register, is an instrument that records wind speed and direction, sunshine, and precipitation.
Q: How does air pressure generally change with altitude?
A: Air pressure generally decreases with increasing altitude.
Q: What are trade winds?
A: Trade winds are a type of planetary wind that blow almost consistently in the same direction throughout the year.
Q: What is the lowest temperature ever recorded on Earth?
A: The lowest temperature ever recorded on Earth is −89.2°C (−128.6°F), recorded on July 21, 1983, at the Soviet Vostok Station in Antarctica.
Q: What are monsoon winds?
A: Monsoon winds are seasonal winds that change their direction according to the season, blowing from sea to land during summer and land to sea during winter.
Q: How does temperature generally vary from the equator to the poles?
A: Generally, temperature is highest near the equator and decreases gradually towards the poles.
Q: What is the difference between low pressure and high pressure areas?
A: In low pressure areas, wind blows towards the center, while in high pressure areas, wind blows outwards from the center.
Q: What is the origin of the word “climate”?
A: The word “climate” is derived from the ancient Greek word “Klimo,” which means “inclination.”
Q: What is the study of weather called?
A: The scientific study of weather is called meteorology.
Q: What is climatology?
A: Climatology is the scientific study of climate.
Q: Why do aircraft create artificial pressure in the cabin?
A: Aircraft create artificial pressure in the cabin to keep passengers comfortable, as the air pressure and oxygen levels decrease at high altitudes.
Q: What are some of the least windy places on Earth?
A: Some of the least windy places on Earth include parts of Brazil, Gabon, Congo, DR Congo in Africa, and Sumatra, Indonesia, and Malaysia.
Q: What is decompression sickness?
A: Decompression sickness can occur when people move quickly from high pressure to low pressure environments, such as ascending to high altitudes too rapidly.
