What are the relative contributions of planets to the Milankovitch Cycles?

Asked by: George Long What contributes to Milankovitch cycles? This wobble is due to tidal forces caused by the gravitational influences of the Sun and Moon that cause Earth to bulge at the equator, affecting its rotation. The trend in the direction of this wobble relative to the fixed positions of stars is known as

What is the reason why there are radiosonde measurements in the atmosphere?

Asked by: George Long What is the purpose of a radiosonde? The radiosonde is a small instrument package that is suspended below balloon filled with either hydrogen or helium. As the radiosonde is carried aloft it measures pressure, temperature, and relative humidity. How does a radiosonde help predict the weather? A transmitter on the radiosonde

How can I describe this data using a graph?

Asked by: Dawn Orr How do you describe data from a graph? A line graph plots data in a single line over time. To describe the graph, follow it’s progress along the horizontal access and describe whether it goes down, up, or stays the same. What are ways to describe a graph? For example, the

Coriolis force in atmospheric/ocean modeling

Asked by: Ashley Alexander What is the role of Coriolis force in atmospheric movement? Outside storm systems, the impact of the Coriolis effect helps define regular wind patterns around the globe. As warm air rises near the Equator, for instance, it flows toward the poles. In the Northern Hemisphere, these warm air currents are deflected

What are these lake-like blue patches in the desert, visible in satellite image?

Asked by: Ashley Alexander What Colour is water in satellite images? Water absorbs light, so it is usually black or dark blue. Sediment reflects light and colors the water. When suspended sand or mud is dense, the water looks brown. How can I view live satellite images? From near real-time satellite views to live feeds,

Lightning moving close to the ground in Magalia, CA last July, months before the Camp Fire

Asked by: Amber Fierro Which state of the USA has been recently affected with lightning sparked fires? California (CNN) Dry lightning has ignited some of the most destructive and costly wildfires in California history, a new study shows. Can forest fires be caused by lightning? Additionally, many rangeland and grass fires are caused by lightning.

How did Australia separate from India?

Asked by: Amber Fierro It was formed by the fusion of Indian and Australian platesAustralian platesThe Australian Plate is a major tectonic plate in the eastern and, largely, southern hemispheres. Originally a part of the ancient continent of Gondwana, Australia remained connected to India and Antarctica until approximately 100 million years ago when India broke

How global was the Bonarelli Oceanic Anoxic Event?

Asked by: Derreck Phutane When did ocean anoxic events occur? It’s known as Oceanic Anoxic Event 2. The Mesozoic era, stretching from 252 to 66 million years ago, is sometimes mistakenly thought of as sort of long and uneventful Pax Dinosauria—a stable, if alien world. But the period was occasionally punctuated by severe climate and

Permian-Triassic mass extinction. Consequences on Earth’s system

Asked by: Derreck Phutane How did the Permian extinction affect the Earth? The Permian extinction was characterized by the elimination of over 95 percent of marine and 70 percent of terrestrial species. In addition, over half of all taxonomic families present at the time disappeared. This event ranks first in severity of the five major

How will global warming affect climate systems like the ENSO or the MJO?

Asked by: Craig Wiseman How will global warming affect ENSO? Climate change is increasing the frequency of extreme El Niño events, leading to intensifying droughts, worsening floods, and shifting hurricane patterns, according to a new study published in the Proceedings of the National Academy of Sciences. Does MJO affect ENSO? There is evidence that the
