NOAA Scientists Hope to Unlock Secrets of Nighttime Thunderstorms

Rick Pantaleo
VOA Scince World Blog
20 May 2015

Most thunderstorms get their incredible energy from the sun's
heat, but some of the storms gain their strength at night,
baffling scientists.

To learn how these storms intensify, the US National Oceanic and
Atmospheric Administration – NOAA plans to keep 20 of its
scientists up late at night for a large intensive field operation
in the US western Great Plains called the Plains Elevated
Convection at Night, or PECAN, over the summer months.

According to NOAA, soon after sunset Earth and its lower
atmosphere tends to lose heat and becomes more stable. These
conditions create a less than an ideal environment for supporting
thunderstorms.

However, many summer thunderstorms, in the US Great Plains, take
shape soon after the sun goes down and sometimes does so without
an obvious trigger.

Conrad Ziegler, PECAN's principal scientist and a research
meteorologist for NOAA's National Severe Storms Laboratory said
that while large nighttime thunderstorms provide an important
source of rain for crops, they can also produce widespread and
potentially dangerous severe weather, excessive rainfall, flash
flooding and unusually frequent cloud-to-ground lightning.

"Weather forecast models often struggle to accurately account for
these," said Ziegler in a NOAA press release. "The PECAN field
campaign will provide us with valuable insights-and improve our
ability to save lives and property through more accurate
forecasts."

NOAA says that its scientists along with other investigators,
students and support staff from eight research laboratories and
14 universities will gather data with appropriately equipped
aircraft, a variety of ground-based instruments, mobile radars
and weather balloons before and during nighttime thunderstorms.

The PECAN researchers will conduct their field investigation from
June 1, 2015 to July 15, 2015 so that they will be able to better
understand just what triggers thunderstorms, what role our
atmosphere plays in supporting the storm's lifecycle as well as
the impact they have on the lives, property, agriculture and
water budget in the US western Great Plains region.

NOAA meteorologists believe that the specially targeted PECAN
observations will eventually lead to improved forecasts of these
potentially damaging storms.

Study: Plankton Are a Major Oxygen Source on Earth

George Putic, KI4FNF
May 26, 2015

Tiny ocean creatures collectively called plankton are mostly
thought of as food for whales and other large marine animals. But
a four-year global study has discovered, among other things, that
plankton are a major source of oxygen on our planet.

Plankton are animals, algae, bacteria and other microscopic
organisms invisible to the naked eye. They inhabit the upper
layers of the world's oceans, seas and freshwater.

In a project called Tara Oceans, led by the French nonprofit
organization Tara Expeditions, 200 scientists from 45 countries
took turns researching plankton aboard a two-mast schooner.

Setting sail in September 2009, the ship, Tara, visited 210
sites, where scientists collected 35,000 samples, researching the
lives, genetic makeup and movement of the tiny creatures.

Chris Bowler, Tara Oceans' scientific coordinator, said the
researchers discovered that plankton are responsible for much of
the well-being of our planet. The creatures are "generating the
oxygen we breathe, removing carbon dioxide from the atmosphere
and generally maintaining this Earth in a state that is habitable
for us human beings," he said.

Bowler said that close to half of the oxygen that we breathe
comes from diatoms — tiny, photosynthesizing algae that inhabit
the sunlit layer of all water bodies. "That basically means every
fifth time that you breathe, you're breathing oxygen which we can
directly trace back to diatoms," he said. "So they're sort of as
important as a tropical rain forest in terms of their global
contribution."

Expedition executive director Romain Troublé said the study
clearly showed that the ocean is the Earth's climate machine.

"We believe that the ocean is also the main driver of the climate
change, the main mitigator in the way that the ocean and the life
in the ocean is storing carbon dioxide, storing heat," he said.
"And this machinery works because the ocean is in good health."

Different groups of scientists studied different things. For
instance, one group cataloged over 40 million previously unknown
plankton genes. Another found that most of the plankton
interactions were parasitic.

The collected data will be used to determine which of the
organisms are most adaptable to changing water conditions.

Results of the first studies were published in the May edition of
the online scientific journal Science, which said that many
analyses would follow.

Galapagos Volcano Eruption Threatens Pink Iguanas

VOA News
May 26, 2015

Officials at Ecuador's Galapagos Islands National Park say a
volcano atop one of the islands has erupted, potentially
threatening a unique species of iguanas.

The nearly 1.8 kilometer-high Wolf volcano is located on Isabela
Island, home to a rich variety of plants and animals typical of
the archipelago that helped inspire Charles Darwin's theory of
evolution.

A statement posted on Twitter by the national park said that
while no human populations are threatened by the eruption, the
island is home to the only population of pink iguanas in the
world.

Ecuador's government was not immediately available for comment on
potential harm to the island's ecosystem.

Park officials say the Wolf volcano had been inactive for 33
years.

In April, unusual activity also was reported at the Sierra
volcano on the same Isabela island, the archipelago's biggest,
where yellow iguanas and giant turtles also live.

The eruption in Ecuador comes on the heels of eruptions in Chile,
another South American country located on the so-called Pacific
Rim of Fire.

Emiliano in Italy has been receiving slow scan television (SSTV)
transmissions from the International Space Station (ISS). The ISS
has been using the PD180 mode of SSTV. Emiliano suggests a
comparison of PD180 with our usual MFSK32 images.

So, let's try it.

The following image is in the PD180 SSTV mode. Its caption: The
Wolf volcano spews smoke and lava on Isabela Island in Galapagos
National Park, May 25, 2015.

MFSK32 will resume after the PD180 SSTV transmission.

That PD180 SSTV image was 637 x 494 pixels. If I were to transmit
an image of the same size in MFSK32, it would take about 16
minutes! In the same 187 seconds required to transmit that PD180
image, here is the same image in MFSK32, 274 x 213 pixels ...
