MétéoMédia - Australia's wildfires are now generating their own weather

Australia s wildfires are now generating their own weather
Digital Writers
mardi, 31 décembre 2019 à 16:18 - The massive fires are generating pyrocumulonimbus clouds, which can start more wildfires on their own.
Australia s enormous and widespread bushfires have now reached the point where they are generating their own weather, creating a feedback loop that will make the already dire situation worse.
That s according to the Bureau of Meteorology office for the state of Victoria, which says it s observed pyrocumulonimbus clouds above eastern parts of the state.
The mechanism by which these clouds form isn t completely understood, but to observers, the clouds will appear very similar to the kind of clouds known to produce thunderstorms. ....

dimanche, 14 avril 2019 à 20:58 - After powerful storms ripped through parts of the southern U.S. Saturday, with fatalities reported, accounts of more injuries and damage have surfaced.
Communities across the southern U.S. are continuing to assess the damage and number of fatalities following a significant severe weather outbreak that originated in east Texas Saturday.
The death toll continues to rise and now includes at least seven, as reported by CNN Sunday evening.
The latest figure includes a Texas woman whose mobile home was destroyed Saturday night. Four other people were injured when the trailer was struck, Houston County Emergency Management Co-ordinator Roger Dickey told CNN. ....

Phil Thomsen writes about the benefits of composting.
Wanganui Midweek
There is a way that we can all do to reduce carbon dioxide build-up – we can remove it from the atmosphere ourselves, through our gardens.
Plants remove CO2 from the atmosphere, converting it into complex foods, which can be used for their own vital functions, or else for food for humans (eg the feijoas and lettuces that we grow in our garden). However, this CO2 is then released back to the atmosphere through decomposition, unless it is retained in a long-term form, such as wood for construction, which is seldom the case with garden plants. ....

Detecting This Specific Gas in an Alien World's Atmosphere May Be a Good Sign of Life

Detecting This Specific Gas in an Alien World s Atmosphere May Be a Good Sign of Life
MATT WILLIAMS, UNIVERSE TODAY
4 APRIL 2021
It is no exaggeration to say that the study of extrasolar planets has exploded in recent decades. To date, 4,375 exoplanets have been confirmed in 3,247 systems, with another 5,856 candidates awaiting confirmation.

In recent years, exoplanet studies have started to transition from the process of discovery to one of characterization.
This process is expected to accelerate once next-generation telescopes become operational.
As a result, astrobiologists are working to create comprehensive lists of potential biosignatures, which refers to chemical compounds and processes that are associated with life (oxygen, carbon dioxide, water, etc.) ....

MétéoMédia - Rare tornado judged 'probable' in Northwest Territories

Rare tornado judged probable in Northwest Territories
Caroline Floyd
lundi, 3 juin 2019 à 20:00 - Not somewhere you hear about a lot of tornadoes, but how rare was it?
It seems June 2 was a day for unusual tornadoes across Canada. While one unexpected twister tore a path through the National Capital Region, another looks to have gone north. Way north, in fact all the way to the Northwest Territories.
Video from Fort Smith, about 300 km south of Yellowknife and right along Alberta s northern border, shows what appears to be a tornado stirring up debris as it swirled through the town on Sunday afternoon around 4 p.m. MDT. ....
