Getting Started: Exploratory Data Analysis of Tropical Cyclones |
In this section you examine the relationship between wind speed and atmospheric pressure for tropical cyclones. The National Hurricane Center routinely reports both of these quantities as indicators of a storm's intensity. The figures in this section assume that you have excluded observations with low wind speeds as described in the "Creating a Bar Chart" section.
