Severe Thunderstorms Will Increase In Frequency As A Result Of Climate Change, Research Finds

Severe thunderstorms may increase in frequency as a result of the changing atmospheric conditions that will accompany climate change, new research has found. The recent research and analysis has revealed that the conditions which favor the development of severe thunderstorms will become much more common in the coming years.

The severe thunderstorms of the near-future will feature stronger winds than we are accustomed to, but, according to the new analysis, tornado numbers should about stay the same. There is some uncertainty with regards to tornadoes though, we’ll likely just have to wait and see…

“Climate model simulations suggest that on average, as the surface temperature and moisture increases the conditions for thunderstorms becomes more frequent. Climate change decreases temperature difference between the poles and the equator. This leads to a decrease in vertical wind shear, which is a major factor determining what type of severe weather occurs. These expectations are supported by a majority of the climate model simulations that have looked at the variables.”

However, the risks of tornadoes and hail “are still open to many questions. The small scale of severe thunderstorms makes it difficult to deal with them with global models. The estimations of their occurrence in the future climate is based on the occurrence of their favorable environments in climate model simulations.”

“According to latest research the intensity of tornadoes will not increase, therefore incidents like in Oklahoma are not expected to be more frequent than today,” said Harold Brooks, who is one of the most well-known researchers of severe thunderstorms from National Severe Storms Laboratory, USA. “Most of the research on severe thunderstorms and tornadoes in climate change has focused on the USA and it is unclear how well the lessons learned there apply to the rest of the world.”

Most severe weather incidents in Finland are caused by phenomena related to thunderstorms such as lightning, strong wind gusts, hail and tornadoes. On average one person is killed every second year because of a lightning strike. Thunderstorms can cause also severe damage to the property because of falling trees and strong winds. On average, about 14 cases of tornadoes are reported in Finland annually. Most of them are quite weak but also some significant cases have been reported in history.

“As climate models are being developed, we are beginning to get more accurate information about the impacts of climate change to severe weather incidents in areas like Finland,” says meteorologist Pauli Jokinen from Finnish Meteorological Institute.

While “extreme” weather (as compared to what we are used to) is nothing to sneer at, it doesn’t truly compare to the other likely effects of climate change — diminishing agricultural productivity, water scarcity in many regions, large-scale migrations and the spread of disease that often accompanies them, and possible large-scale war/social breakdown.

  1. Tropical temperatures are constrained by the properties of H2O
    Thunderstorm Thermostat Hypothesis — Polar regions are not.

    As we cool into the Ice Age,
    Jet streams will move closer to the Equator.

    Building a backyard greenhouse will be one of the best investments
    you will ever make.
    It’s time to escape the food industries poison laced fruits and vegetables
    and start growing them in your own DIY greenhouse.. All year round!

    Not only will you be able to grow more flowers, herbs, fruits,
    vegetables and plants all year round, but you’ll be proud to

    know that you made something with your own two hands.

  3. — what do you mean by “..WILL increase”? The severe storms ARE ALREADY increasing! It’s widely reported – globally – and has been the trend for the last 4/5 years now. New record flooding/droughts/rainstorms (NYC, May, new record)..heat (Pakistan, May)…the list is huge. Great article Nathan. This should be required reading to all – especially those members of the US Congress who, in their support of 1) tar sands oil and 2) methane-releasing fracking, are by definition either/or 1) ignorant 2) apathetic 3) severely unintelligent or 4) openly hostile to the present and future human race. Great story, Nathan.
