The letters in the top row stand for months: January, February, etc. The bars and numbers convey the following information: The blue bars represent the average amount of precipitation (rain, snow etc.) that falls in each month. The blue numbers are the amount of ...
Over the past 20 years, an average of 42 tornadoes have occurred in the U.S. in February, fewest of any month. But, as always with tornado counts, there is substantial year-to-year variability.
Weather stations typically have these following instruments: Thermometer for measuring air and sea surface temperature; Barometer for measuring atmospheric pressure; Hygrometer for measuring humidity; Anemometer for measuring wind speed; Pyranometer for measuring solar radiation; Rain gauge for measuring liquid precipitation over a set period ...
Pico del Este averages 171.09 inches (4,346 mm) of rainfall yearly while Magueyes Island averages only 29.32 inches (745 mm) a year. [ 81 ] [ 82 ] Despite known changes in tropical cyclone activity due to changes in the El Niño/Southern Oscillation (ENSO), [ 83 ] there is no known relationship between rainfall in Puerto Rico and the ENSO cycle.
Rainfall character is decided by the total amount of rain that has fallen in a set period (usually 1 hour) by counting the number of pulses during that period. Algorithms may be applied to the data as a method of correcting the data for high-intensity rainfall. Tipping bucket rain gauge recorder Closeup of a tipping bucket rain gauge recorder chart
The first devices used to measure weather phenomena were the rain gauge, the anemometer and the hygrometer. The 17th century saw the development of the barometer and the Galileo thermometer while the 18th century saw the development of the thermometer with the Fahrenheit and Celsius scales.

It forms part of a standard weather station and holds instruments that may include thermometers (ordinary, maximum/minimum), a hygrometer, a psychrometer, a dewcell, a barometer, and a thermograph. Stevenson screens may also be known as a cotton region shelter, an instrument shelter, a thermometer shelter, a thermoscreen, or a thermometer screen.
