Typically, the majority of Atlantic tropical systems travel westward at lower latitudes and then curve to the north and northeast upon reaching the belt of the prevailing westerly winds. With this directional pattern, storms like Florence (#6) that do not curve until passing about 75°W, ______ likely impact land before turning northward.
a.will
b.will not
Storms that form in or travel to the Caribbean Sea or the Gulf of Mexico are virtually certain to impact land areas. There were multiple examples of these tracks in 2018. ______ is one particular example.
a.Tropical Storm Alberto (#1)
b.Hurricane Chris (#3)
c.Hurricane Helene (#8)
d.Tropical Storm Joyce (#10)
One function hurricanes and tropical cyclones perform in the global weather system are to transport heat and moisture from tropical oceans to higher latitudes. For example, look at the path of Tropical Storm Beryl (#2). They originated as tropical systems over warm waters south of 15°N latitude, eventually attaining hurricane strength, later weakening and dissipating beyond 35°N latitude. The storms’ tracks imply that these cyclones ______ transport energy and moisture to higher latitudes.
a.did
b.did not
). Despite this lesser number of major hurricanes, the ones that did occur in the Atlantic were particularly devastating (e.g., Florence & Michael) with their landfalls in the U.S. By contrast, in the Pacific basin, there were a total of 22 named storms, which was only five short of the all-time record of 27 set in 1992. This seasonal uptick in the Pacific was very likely the result of abnormally warm sea-surface temperatures (SSTs), helping to provide a favorable breeding ground. By many measures, the 2018 hurricane season was indeed significant, one not to be forgotten for a long time.
In sum, there were 14 named Atlantic-basin tropical storms in 2018, which includes 7 hurricanes with 2 becoming major hurricanes. This compares to 1966–2009 long-term averages for the Atlantic basin of 11.3 named tropical storms, 6.2 becoming hurricanes with 2.3 being major hurricanes. The 2010, 2011, 2012 seasons were all more active, with 19 named tropical storms each. The 2017 season was more active than 2018.
**Figure 7B-2** is the track map of Atlantic basin tropical cyclones for the 2018 season from the National Hurricane Center (NHC) [Link 7B-3](#). The track of each named storm is shown numbered at the beginning and end of its track. The names of the storms, corresponding to the numbers along with strength and dates of existence, are in a table to the upper left. Recall that hurricane wind threshold speed is 64 kts (74 mph). The type, MH, in the table and legend of [Figure 7B-1](#) defines ‘Major Hurricanes’ as category 3, category 4, and category 5 on the Saffir-Simpson scale.](https://content.bartleby.com/qna-images/question/4075dd7b-7cf0-4080-a9ab-c20ff4793850/cb7f495b-f16f-45a4-889d-5be17c5cb012/3ff56qp_processed.png)
