Standard Deviation of Maximum Monthly Wind Speeds given Wind Speed with r-year Return Period Solution

STEP 0: Pre-Calculation Summary
Formula Used
Standard Deviation of Maximum Monthly Wind Speeds = (Wind Speed with r Year Return Period-Mean Value of Maximum Monthly Wind Speeds)/(0.78*(ln(12*Return Period of Wind)-0.577))
σm = (Ur-Um)/(0.78*(ln(12*Tr)-0.577))
This formula uses 1 Functions, 4 Variables
Functions Used
ln - The natural logarithm, also known as the logarithm to the base e, is the inverse function of the natural exponential function., ln(Number)
Variables Used
Standard Deviation of Maximum Monthly Wind Speeds - Standard Deviation of Maximum Monthly Wind Speeds refers to the statistical measure that quantifies the amount of variation in the maximum wind speeds recorded each month over a specified period.
Wind Speed with r Year Return Period - (Measured in Meter per Second) - wind speed with r year Return Period refers to the need for wind speed return levels corresponding to return periods.
Mean Value of Maximum Monthly Wind Speeds - (Measured in Meter per Second) - Mean Value of Maximum Monthly Wind Speeds refers to the average of the highest wind speeds recorded each month over a specified period.
Return Period of Wind - Return Period of Wind is an average time or an estimated average time between events such as winds.
STEP 1: Convert Input(s) to Base Unit
Wind Speed with r Year Return Period: 32.6 Meter per Second --> 32.6 Meter per Second No Conversion Required
Mean Value of Maximum Monthly Wind Speeds: 17.5 Meter per Second --> 17.5 Meter per Second No Conversion Required
Return Period of Wind: 50 --> No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
σm = (Ur-Um)/(0.78*(ln(12*Tr)-0.577)) --> (32.6-17.5)/(0.78*(ln(12*50)-0.577))
Evaluating ... ...
σm = 3.32632445851365
STEP 3: Convert Result to Output's Unit
3.32632445851365 --> No Conversion Required
FINAL ANSWER
3.32632445851365 3.326324 <-- Standard Deviation of Maximum Monthly Wind Speeds

What is Return Period?

Extreme conditions in coastal engineering are often described in terms of return values and return periods. A Return Period, also known as a recurrence interval or repeat interval, is an average time or an estimated average time between events such as earthquakes, floods, landslides, or river discharge flows to occur.

What is Standard deviation?

Standard Deviation is a measure which shows how much variation (such as spread, dispersion, spread,) from the mean exists. The standard deviation indicates a “typical” deviation from the mean. It is a popular measure of variability because it returns to the original units of measure of the data set.
