How some tropical trees benefit from being struck by lightning nph.onlinelibrary.wiley.com/do

"The lightning's power cleanses these trees of parasitic #vines. It also zaps trees nearby, reducing competition. Dipteryx oleifera, a towering presence in #Panama's forests, is particularly adept at thriving after enduring events that are deadly to most other trees."

Tropical tonka bean trees (Dipteryx oleifera) not only survive lightning strikes, but appear to benefit from them. Lightning strikes on tonka bean trees kills liana vines that are growing on the trees, and kills or damages surrounding trees.

"Storm clouds generate massive electrical potentials...but nowhere is the electric field strong enough to ionize the air and start a miles-long branching bolt. Something needs to create the initial spark...

Using precise radio-wave detection in three dimensions, scientists at Los Alamos National Laboratory have determined that the sparks are provided by cosmic rays...atomic-scale particles traveling at incredible speeds..."

Interlude: Galactic Lightning And a real planetary alignment Markael Luterra, Mar 27, 2025 Image of a grey sky over water, small boats and rocks in the foreground, above a lightning bolt reaches from the sky to the water. Atef Ouni, CC BY-SA 4.0 <https://creativecommons.org/licenses/by-sa/4.0>, via Wikimedia Amidst the chaotic headlines last week, the news you probably didn’t hear is that scientists have effectively confirmed that cosmic rays spark lightning. I want to share why I find this absolutely wondrous, which means I first need to try to describe some physics at the boundaries of my understanding. There is a problem with lightning. The problem is that it shouldn’t actually happen. "When these extra-powerful particles collide with atoms in the atmosphere, at a rate of about 15 per square mile per second, they generate a chain reaction of nuclear physics, each impact creating more particles like a series of billiard breaks until over a million balls are in motion and the energy has finally been exhausted. This is called an “air shower”, and it’s happening all around us all of the time, and it’s how our atmosphere protects our bodies and all life on Earth."

The world regulated sulfur in ship fuels − and the lightning stopped

<<If you look at a map of lightning near the Port of Singapore, you’ll notice an odd streak of intense lightning activity right over the busiest shipping lane in the world. As it turns out, the lightning really is responding to the ships, or rather the tiny particles they emit.>>

The ConversationThe world regulated sulfur in ship fuels − and the lightning stoppedAn unplanned experiment takes scientists closer to solving a long-standing mystery: To what extent, if any, have human-created emissions influenced thunderstorms?

"The recent 7-fold change in allowable fuel sulfur by the International Maritime Organization allows us to test the sensitivity of the lightning to changes in ship plume aerosol number-size distributions. We find that, across a range of atmospheric thermodynamic conditions, the previously documented enhancement of lightning over the shipping lanes has fallen by over 40 %."

acp.copernicus.orgLightning declines over shipping lanes following regulation of fuel sulfur emissionsAbstract. Aerosol interactions with clouds represent a significant uncertainty in our understanding of the Earth system. Deep convective clouds may respond to aerosol perturbations in several ways that have proven difficult to elucidate with observations. Here, we leverage the two busiest maritime shipping lanes in the world, which emit aerosol particles and their precursors into an otherwise relatively clean tropical marine boundary layer, to make headway on the influence of aerosol on deep convective clouds. The recent 7-fold change in allowable fuel sulfur by the International Maritime Organization allows us to test the sensitivity of the lightning to changes in ship plume aerosol number-size distributions. We find that, across a range of atmospheric thermodynamic conditions, the previously documented enhancement of lightning over the shipping lanes has fallen by over 40 %. The enhancement is therefore at least partially aerosol-mediated, a conclusion that is supported by observations of droplet number at cloud base, which show a similar decline over the shipping lane. These results have fundamental implications for our understanding of aerosol–cloud interactions, suggesting that deep convective clouds are impacted by the aerosol number distribution in the remote marine environment.
