Harder Winters, Stronger StormsRead More about Harder Winters, Stronger Storms
About 30 massive, intricate computer networks serve the scientists who stand at the forefront of climate change research. Each network runs a software program comprised of millions of lines of code. These programs are computational models that combine the myriads of physical, chemical and biological phenomena that together form the climate of our planet. The models calculate the state of Earth’s atmosphere, oceans, land and ice, capturing past and present climate variability and using the data to predict future climate change.

Breakfast of ChampionsRead More about Breakfast of Champions
Even the smallest organism can have a major influence on the evolution of life on Earth. Microscopic algae that inhabit the sunlit waters of the ocean surface are not only responsible for about half of the photosynthesis on the planet but are also valuable as a nutrient-rich food source sustaining the entire marine ecosystem. In their recently published study, Prof. Itay Halevy and Dr.

Jupiter’s Great Red Spot Measured in Depth for the First TimeRead More about Jupiter’s Great Red Spot Measured in Depth for the First Time
Jupiter’s Great Red Spot is up there with the rings of Saturn and the blue marble of Earth for solar system icon status. In a study published today in Science, Weizmann Institute of Science researchers and their collaborators on NASA’s Juno mission to Jupiter report that this spot – really a giant, persistent storm – extends to a depth of about 500 kilometers below the planet’s clouds.

Jupiter's Super Polar Cyclones are Here to StayRead More about Jupiter's Super Polar Cyclones are Here to Stay
Until recently, before NASA’s Juno space probe entered its orbit around the planet Jupiter, no one knew that powerful cyclones, approximately the size of Australia, rage across its polar regions. Jupiter's storms, as opposed to their earthly variety, do not disperse, hardly change, and are clearly not associated with flying rooftops and damp weather reporters.

Students on the blue marble - Shlomit SharoniRead More about Students on the blue marble - Shlomit Sharoni
Shlomit Sharoni has successfully completed her PhD at the Department of Earth and Planetary Sciences, and is currently a postdoctoral researcher at Prof. Itay Halevy’s group. She is a modern-day Renaissance woman, in addition to her research career, she is also an aerial acrobatics instructor and a bass guitar player. She has an adorable 3-year old daughter, and currently lives in Eilat with her family. During her PhD, Shlomit investigated the impact of the elemental composition of microscopic algae on the oceanic environment, both in the present and in the geological past.

How Bushfire Smoke Traveled Around the WorldRead More about How Bushfire Smoke Traveled Around the World
It’s not just how hot the fires burn – it’s also where they burn that matters. During the recent extreme fire season in Australia, which began in 2019 and burned into 2020, millions of tons of smoke particles were released into the atmosphere. Most of those particles followed a typical pattern, settling to the ground after a day or week; yet the ones created in fires burning in one corner of the country managed to blanket the entire Southern hemisphere for months.

In the year 2000, Prof. Dan Yakir, the 2019 Israel prize recipient for Earth sciences, established the research station in the Yatir forest in order to explore the interplay between vegetation, the atmosphere, and the climate system. Recent findings from data analysis of the measurements conducted at the station indicate a considerable carbon sink potential in semiarid soils and forest plantations, and imply that afforestation of even 10% of semiarid land area under conditions similar to that of the study site, could sequester ~400 billion kg of carbon per year over several decades.

2020 wasn’t the easiest year, one might say it was somewhat apocalyptic. Still, it also had some bright moments. One of them, for the department of Earth and Planetary Sciences, was the addition of Rei Chemke as a principal investigator. Rei’s research focuses on climate dynamics. He’s interested in large scale processes, particularly in the atmospheric and oceanic flows, temperature and sea ice due to both natural and anthropogenic processes.

Israelis are not usually known for their exceptional punctuality, but Prof. Yohai Kaspi and Dr. Eli Galanti of the Weizmann Institute of Science’s Earth and Planetary Sciences designed a clock so accurate, it will lose less than a second in ten million years. Kaspi is the PI of the atmospheric science experiment of the European Space Agency’s JUICE mission to Jupiter. The clock will be used to perform atmospheric radio-occultations of Jupiter in order to study the properties of its atmosphere.

Plastic is Blowing in the WindRead More about Plastic is Blowing in the Wind
As the plastic in our oceans breaks up into smaller and smaller bits without breaking down chemically, the resulting microplastics are becoming a serious ecological problem. A new study at the Weizmann Institute of Science reveals a troubling aspect of microplastics – defined as particles smaller than 5 mm across. They are swept up into the atmosphere and carried on the wind to far-flung parts of the ocean, including those that appear to be clear.

Clouds: We see them as objects with clear-cut shapes and outlines. The satellites that collect cloud data and the climate models built on this data work on this supposition as well. But the line between “cloudy” and “clear” is much hazier than we think.

Cool in the Shade: How Ice Could Exist Near the Lunar SurfaceRead More about Cool in the Shade: How Ice Could Exist Near the Lunar Surface
If humans are to establish any sort of settlement on the Moon, they might do so near one of its poles, where its meager supply of water is stored in the form of ice. That ice has been detected in difficult-to-reach spots: at the bottoms of large, deep craters, down where sunshine cannot reach and temperatures remain below -160o Centigrade.

NASA’s Next Destination? Israelis Hopeful as Trident Team in the FinalsRead More about NASA’s Next Destination? Israelis Hopeful as Trident Team in the Finals
If life does exist outside of Earth in our Solar System, it could be hiding in subterranean oceans flowing under the surface of icy moons. One of the most promising candidates for such an underground liquid body is Triton – aptly named for the son of the sea god Neptune – the planet around which it orbits.
