Latest Atmospheric dynamics Stories
For decades, scientists have witnessed the oxygen minimum zones (OMZ) in the tropical oceans expanding, reducing the habitat of some types of fish in the process, and now they finally know why this phenomenon is occurring.
Climate scientists have finally solved the mystery as to why the equatorial Pacific trade winds, which were expected to get weaker due to increasing greenhouse gas levels, have actually gotten stronger in recent years.
Ocean waves, the hot sun, sea breezes -- the right combination makes a great day at the beach. A different combination makes a killer hurricane. The complex interactions of the ocean and the air above it that can create such different outcomes are not yet fully known. Scientists would especially like to understand the role that the daily heat of the sun plays in creating winds.
Variations in high-altitude wind patterns expose particular parts of Europe, Asia and the US to different extreme weather conditions, a new study has shown.
Every ten days, the NASA/French Space Agency Jason-2 satellite maps all the world's oceans, monitoring changes in sea surface height, a measure of heat in the upper layers of the water. Because our planet is more than 70% ocean, this information is crucial to global forecasts of weather and climate.
Last winter's curvy jet stream pattern brought mild temperatures to western North America and harsh cold to the East. A University of Utah-led study shows that pattern became more pronounced 4,000 years ago, and suggests it may worsen as Earth's climate warms.
ENERTIA® CEO Michael Sykes announces three new Extreme EX models of the Award-Winning Green kit-home series, with beefed up thermal mass for more inertia, and reflective hidden internal surfaces
A 1,000-year period of pronounced climate variability occurring in Europe could have been the result of changes in the sun’s energy output, according to research published in Sunday’s edition of the journal Nature Geoscience.
California residents plagued by drought just got some good news from the National Oceanic and Atmospheric Administration: El Niño is coming – maybe.
During very strong El Niño events, sea level drops abruptly in the tropical western Pacific and tides remain below normal for up to a year in the South Pacific, especially around Samoa.
Say it’s not so, but we could be very well on the verge of entering into an EL-Nino cycle soon. How soon? The latest forecast issued by the Climate Prediction Center has upped the chances of seeing EL-Nino this year now at 61% with the favorable time period pointing towards the 3rd quarter (July-September). What does this mean to you? Well it all depends on where you’re living as EL-Nino has a wide array of impacts that are different everywhere around the globe. Here are a few...
A look at the temps from the 4th show that another colder pocket of air is moving into the region. Aug 29: The max temps warmed to 1C, while the overnight lows dropped to 0C. Aug 30: A burst of colder air was over the polar cap as high temps only made it to -3C, and the overnight lows dropped to -6C. Aug 31: Brought a touch of warmer air back into the region as high temps rose back to 1C, while the overnight lows hit -2C. September 1: High temps again rose to 1C, while overnight lows...
Today on Weather Pack we are going to examine the surface wind around a mature low pressure system, which means that the low pressure has an occluded front associated with it. Yellow Star: The forecasted surface winds would be out of the Northwest as the flow behind the low is counter-clockwise. Green Star: Anyone that is forecasting for the green star would be looking at the winds coming from the South-Southeast just right ahead of the warm front of the low pressure system. Red...
Many forecasters new and old run across certain things that just don’t get picked up in the weather models that we use to prepare our weather forecast. This is why I have created weather guides for anyone that is getting ready to or just wants to find out more about the weather in their area. (Here are a few forecaster guide tips to helping prepare a better weather forecast) Elevation: North: Look for a gradual rise. South: Look for no major elevation changes. West: There is a...
When it comes to wind, more and more people are turning to it as alternative option for electricity. One has to wonder what kind of impacts would be created by the different cycles of ENSO. The above graph has been done for Boston MA. The month of choice was to run it for March of all three cycles. Normal Cycle: (When we are in between EL-Nino and La-Nina) winds averaged around 0-5mph 9% of the month of March. While 6-10mph average winds occurred more often with 35%. And then winds in the...
- A pivoted catch designed to fall into a notch on a ratchet wheel so as to allow movement in only one direction (e.g. on a windlass or in a clock mechanism), or alternatively to move the wheel in one direction.
