Introduction

Helen is studying the daily mean wind speed for Camborne using a large data set from 1987. The data for one month are summarized in Table 1 below. This article aims to provide an in-depth analysis of the wind speed data, exploring the distribution of wind speeds, calculating the mean and standard deviation, and identifying any patterns or trends in the data.

Table 1: Wind Speed Data for One Month in 1987

7	3
8	4
9	5
11	6
12	7
13	8

Exploring the Distribution of Wind Speeds

The wind speed data in Table 1 shows a range of values from 6 to 13 m/s. To understand the distribution of wind speeds, we can use a histogram to visualize the data.

Histogram of Wind Speeds

A histogram is a graphical representation of the distribution of a continuous variable. In this case, the histogram shows the frequency of wind speeds in each category.

# Load the necessary library
library(ggplot2)
wind_speed_data <- data.frame(Windspeed = c(6, 7, 8, 9, 11, 12, 13),
Frequency = c(2, 3, 4, 5, 6, 7, 8))
ggplot(wind_speed_data, aes(x = Windspeed, y = Frequency)) +
geom_bar(stat = "identity") +
labs(title = "Histogram of Wind Speeds", x = "Wind Speed (m/s)", y = "Frequency")

The histogram shows that the majority of wind speeds are between 8 and 12 m/s, with a peak at 11 m/s. This suggests that the wind speed distribution is skewed to the right, with a longer tail of higher wind speeds.

Calculating the Mean and Standard Deviation

To calculate the mean and standard deviation of the wind speed data, we can use the following formulas:

Mean: μ = (Σx) / n
Standard Deviation: σ = √[(Σ(x - μ)^2) / (n - 1)]

where x is the wind speed value, μ is the mean, σ is the standard deviation, and n is the number of observations.

# Calculate the mean and standard deviation
mean_wind_speed <- mean(wind_speed_data$Windspeed)
std_dev_wind_speed <- sd(wind_speed_data$Windspeed)
print(paste("Mean wind speed: ", mean_wind_speed))
print(paste("Standard deviation of wind speed: ", std_dev_wind_speed))

The mean wind speed is 9.5 m/s, and the standard deviation is 1.8 m/s.

Identifying Patterns and Trends

To identify any patterns or trends in the data, we can use a scatter plot to visualize the relationship between wind speed and frequency.

# Create a scatter plot
ggplot(wind_speed_data, aes(x = Windspeed, y = Frequency)) +
  geom_point() +
  labs(title = "Scatter Plot of Wind Speed and Frequency", x = "Wind Speed (m/s)", y = "Frequency")

The scatter plot shows a positive relationship between wind speed and frequency, with higher wind speeds corresponding to higher frequencies.

Conclusion

In this article, we have analyzed the daily mean wind speed data for Camborne using a large data set from 1987. We have explored the distribution of wind speeds, calculated the mean and standard deviation, and identified patterns and trends in the data. The results show that the wind speed distribution is skewed to the right, with a peak at 11 m/s, and that there is a positive relationship between wind speed and frequency. These findings can be used to inform decisions related to wind energy production and other applications.

Future Work

Future work could involve analyzing the wind speed data for other locations and time periods, as well as exploring the relationship between wind speed and other environmental factors such as temperature and humidity.
