Extreme Storms: The recent bomb cyclone in the United States and tropical cyclones in southeast Africa

Climate change causes severe weather.

“In all probability it is a result of climate change and indicative of things to come.”

By Dr. John J. Hidore

A Bomb Cyclone Forms in the US Midwest

A bomb cyclone is a low pressure system in which the central pressure rapidly drops by at least 24 millibars (mb) in 24 hours or less. On March 12-14 winter storm Ulmer moved over the Midwest and Southeastern United States. In Ulmer the central pressure dropped 26 mb in 16 hours. All time low pressure records were set in Colorado, Texas, and New Mexico. The central pressure dropped to 968 mb on March 13. The extreme pressure gradient in the storm created winds of 100mph or more over in Texas and New Mexico. Blizzard conditions and whiteouts occurred over a wide area. Thunderstorms and tornadoes were widespread during the storm.

An EF 1 tornado hit Dexter, NM. This was the earliest tornado ever recorded in a calendar year in the state of New Mexico. The storm produced damaging winds in Texas as well.. As the storm moved south and east over two days it spawned widespread tornadoes.

Climate change increases the likelihood of severe weather.

Tropical Cyclones in Southeastern Africa

The storm season in the Indian Ocean so far in 2019 has been extensive. There have already been more than the usual number of storms. Mozambique on the southeastern coast of Africa had not experienced a tropical cyclone since satellite monitoring of the earth began. That changed big time this spring when Cyclone Idai came ashore. It turned out to be among the most destructive weather events to occur in Africa, if not the southern hemisphere. The storm had winds measured at over 175 km/h (105 mph) as it reached shore near the port city of Beiria, Mozambique. The storm produced widespread flooding which added to the wind damage. A stretch of land 50km (30mi) long adjacent to the Buzi River was flooded. In places the flood water was six meters (19 1/2 feet ) deep. Parts of Zimbabwe and Malawi were also effected.

The government of Mozambique announced a confirmed death total of 200 and an estimated 100,000 people needed rescuing from the flood waters near Beira. Some of those rescued were without food or drinkable water for as many as three days. Families were split up, some members dying in the flood. The death toll may have exceeded more than 1000. In Zimbabwe a government statement indicated at least 98 died and another 200 missing. Following the storm the president of Mozambique declared three days of mourning.

Only a few weeks later Cyclone Kenneth came ashore in Mozambique It is the first time since records have been kept that two cyclones reached the country in the same season. Again there was extensive flooding.

Our Changing Climate

The big question is whether this event is indicative of climate change or just a matter of chance. In light of storm activity in the Indian Ocean in all probability it is a result of climate change and indicative of things to come.
