Tropical Cyclone Counts Bar/Column Chart
Tropical cyclones are sometimes called hurricanes or typhoons. Some areas of the world have more tropical cyclones than others. The number of tropical cyclones from 1842 - 2018 is shown on the map below.
In this lesson, we will study the map to identify patterns of tropical cyclones, then use these findings to help us analyze a type of graph called a bar/column chart.
Section A: Identify Patterns of Tropical Cyclones on the Map
- Looking at the above map of tropical cyclone data, which color shows areas with the least hurricanes? Which color values on the map show areas with the most hurricanes?
- On the blank map below, draw a box around the area between 60°- 65° East and 10° - 20° North.
Section B: Analyze the “Number of Tropical Cyclones by Latitude” bar chart and answer questions below.
(Notice, the orange bars represent the amount of hurricanes at 60° East for the latitudes between 10° North and 20° North. The blue bars represent the number of hurricanes at 65° East for the latitudes between 10° North and 20° North.)
- What was the total number of tropical cyclones at each latitude between 60° and 65° East?
- Which latitude had the highest number of tropical cyclones between 60° and 65° East?
- How many more tropical cyclones were at 14° N than at 15° N between 60° and 65° East?
- How many fewer tropical cyclones were at 11° N than at 10° N between 60° and 65° East?
