July 2022 Tropical Cyclones Report

Summary

Nine named storms occurred across the globe in July. Five of those reached tropical cyclone strength (74 mph), and two (Hurricanes Bonnie and Darby) reached major tropical storm strength (111 mph). These counts are all near their 1991-2020 averages for July. The global accumulated cyclone energy (ACE: an integrated metric of the strength, frequency, and duration of tropical storms) was also near normal in July. The tropical cyclone activity for January-July remains slightly below normal.

The North Atlantic had two tropical storms during July. Bonnie became a tropical storm on July 1 in the southwestern Caribbean and maintained tropical storm strength (40-73 mph) as it crossed Central America. Bonnie intensified to a major hurricane over the East Pacific. Tropical Storm Colin was a short-lived storm along the Carolina coast. The Atlantic activity for July and January-July are both near normal.

The East Pacific had five named storms including four hurricanes. Two of those (Bonnie and Darby) became major hurricanes. These numbers are all above normal for July, and the July ACE was about twice the 1991-2020 average. The season January-July East Pacific activity has also been above normal.

The West Pacific only had two named storms including Typhoon Chaba. This activity is much quieter than normal, and the ACE for July was the sixth lowest since 1981. Similarly, the West Pacific has been much below normal for January-July, including the third lowest ACE since 1981.

The only other named storm during July was a weak tropical storm near Australia, which was not named by the Australian Bureau of Meteorology. The lack of activity in these other basins was normal for July.

Data Description

The data in this report are derived from NCEI's IBTrACS dataset (Knapp et al. 2010; Schreck et al. 2014). IBTrACS tropical cyclone track and intensity data from agencies and sources around the globe. In this report, data from NOAA's National Hurricane Center (NHC) are used for the North Atlantic and East Pacific. The other basins use data from the U.S. Military's Joint Typhoon Warning Center (JTWC).

Historical values use the "best track" data that have been analyzed by forecasters after the season using all available data. Operational procedures and observing systems have changed with time and between regions, which makes these data heterogeneous. Intensity data are generally the most reliable since the early 1970s in the Atlantic (Landsea and Franklin 2013) and since the mid-1980s in other regions (Chu et al. 2002). The number of short-lived storms (≤2 days) has also increased since around 2000 due to improvements in observations and analysis techniques (Landsea et al. 2010).

Values for the current year are provisional values from the operational forecast advisories. IBTrACS obtains these from NCEP's TC Vitals, the NCAR Tropical Cyclone Guidance Project, and NHC provisional data. These values are subject to change during the post-season best track analysis. They also only include 6-hourly storm fixes, which means they may miss special advisories at landfall, peak intensity, etc.

The tropical cyclone seasons in the Southern Hemisphere begin in July and end in June, while the Northern Hemisphere seasons are counted from January to December. Storms are counted in all basins, months, and years in which they occur, which means some storms may appear more than once. However, the global totals only include each storm one time.
