The Standard Height of a Standard Rain Gauge
A rain gauge is a meteorological instrument used to measure the amount of precipitation in a specific area over a period of time. The height of a standard rain gauge is designed to ensure accurate and consistent measurements while minimizing interference from environmental factors such as wind and splashing.
-
Standard Design: The rain gauge is typically cylindrical in shape and mounted at a specific height above the ground to avoid obstructions and ensure accurate readings.
-
Height Requirement: The standard height for installing a rain gauge is 30 cm above the ground. This is determined to minimize the impact of wind and splashing rain while maintaining accessibility for measurement.
-
Calibration and Accuracy: The height is standardized internationally to ensure consistency in rainfall data collection across different regions.
Analyzing the Given Options
-
Option 1: 10 cm (Incorrect)
-
A height of 10 cm is too low and may result in inaccurate measurements due to rain splashing or obstructions from nearby objects.
-
-
Option 2: 20 cm (Incorrect)
-
A height of 20 cm is still lower than the standard requirement and may lead to inaccurate readings due to interference from environmental factors.
-
-
Option 3: 30 cm (Correct)
-
The standard height of a rain gauge is 30 cm above the ground. This height ensures accurate and consistent measurements while minimizing the impact of environmental factors.
-
-
Option 4: 50 cm (Incorrect)
-
A height of 50 cm is higher than the standard, which might affect the accessibility of the gauge and lead to inconsistencies in data collection.
-
Conclusion: The correct answer is Option 3: 30 cm.
