29 Questions
What is the normal range for barometer readings?
29.8-30.2 inHg
What does a quick drop in barometric pressure usually indicate?
Rain or storm, or even snow if it's cold enough
What is used to measure wind direction?
Wind vane
How is wind speed typically recorded?
In meters per second (m/s) or kilometers per hour (km/hr)
How is cloud cover recorded?
Based on height (high, medium, low)
How is sunshine duration measured?
Using a sunshine recorder with a strip of special card
What is the primary factor that determines the characteristics of tropical rainforest and hot desert ecosystems?
Latitude
How does latitude affect the amount of solar radiation received in an area?
Lower latitudes receive more intense solar radiation than higher latitudes.
What is the primary reason that water bodies and land masses have different heating and cooling rates?
Water has a higher specific heat capacity than land.
How do ocean currents affect the climate of coastal regions?
Warm ocean currents raise the temperature of coastal regions in winter and lower it in summer.
How does altitude affect temperature?
Temperature decreases with increasing altitude.
How do winds affect the temperature of a region during different seasons?
Winds from the land lower the temperature in winter and raise it in summer.
What do high clouds mainly consist of?
Ice crystals
In what form do low clouds primarily exist?
Water droplets
How are medium clouds typically composed?
Primarily of ice crystals with some water droplets
What is the main distinguishing feature of equatorial climate?
Lack of distinct seasons
What is a common characteristic of hot desert climate?
Low levels of humidity
Which factor does NOT influence climate according to the text?
Atmospheric pressure
How does cloud cover affect the amount of insolation received by the surface?
Decreases the amount of insolation
What is the impact of cloud cover on nighttime temperatures?
Increases nighttime temperatures
How does low air pressure contribute to rain formation?
Leads to cooling and condensation of air
Why are hot deserts often located in high-pressure areas?
Sinking air in high pressure inhibits rain formation
Where do low-pressure systems that lead to rain formation often occur?
Equatorial regions and mountain barriers
What is the purpose of placing weather instruments away from obstructions like trees, balconies, and buildings?
To ensure accurate measurements by avoiding interference
How is the maximum temperature measured using a maximum-minimum thermometer?
The bottom of the index or pin indicates the maximum temperature
Why is a rain gauge typically placed 30 cm above the surface?
To ensure accurate measurements by avoiding interference from the ground
What is the purpose of a wind vane in weather measurement?
To determine wind direction
How is relative humidity measured using a wet and dry bulb thermometer (hygrometer)?
By taking the difference between the wet and dry bulb readings and referring to a relative humidity table
What is the purpose of a Stevenson screen in weather measurement?
To house thermometers and protect them from direct sunlight and precipitation
