With the coldest Winter Olympics in decades, many athletes are in their element, preferring the chill to warmer games in years past. With the cold has come strong and gusty west to northwest winds, which have postponed competitions and threatened athletes’ safety and performance on the slopes.Topics: WeatherOps | Live Events |

The northeast monsoon refers to the seasonal winds that flow southward from the cold Asian continent as strong high pressure develops over Siberia during winter. These cold, dry north to northeast winds flow from the Siberian high across Southeast Asia from about October through March. They surge southward with the passage of low-pressure systems in the midlatitudes, cooling ocean temperatures.
The Australian tropical cyclone season officially began on November 1, 2017, but the first tropical cyclone didn’t form until November 22. Through the first few weeks of the season, atmospheric conditions were unfavorable for development due to strong wind shear on the order of 40 knots and extensive dry air. Later in the month, wind shear decreased, and moisture increased south of Java and across the Timor Sea.
A prescribed, or controlled, burn is a fire that is strategically ignited for the benefit of communities, ecosystems, and the environment. It’s a useful tool for managing plant and animal species and suppressing non-native ones. A good example is the use of fire to remove mid-story brush in the W.G. Jones State Forest near the Woodlands, Texas. This 1,700-acre forest is home to the endangered Red-cockaded Woodpecker, which builds its nesting cavities in mature living pines. Fire maintains a mature open pine forest by removing the hardwood species that develop beneath them.Topics: WeatherOps | Wildfire |
The weather patterns that affect northern Australia are monsoonal. There are distinct wet and dry patterns, driven by seasonal winds. From December through March, northeast monsoon winds flow across Southeast Asia in response to the strong Siberian High and cold Asian continent. Gaining moisture as they traverse the South China Sea, these winds turn northwesterly over the Java Sea south of the equator. By January this persistent northeasterly flow across Southeast Asia forces the monsoon trough, part of the Intertropical Convergence Zone (ITCZ), into its southernmost position near 10°S. The monsoon trough serves as a focus for the inflow of moist tropical air and brings enhanced west to northwesterly winds, cloudiness, and heavy rainfall to portions of northern Australia.Topics: WeatherOps | Tropical |
It's windy outside, the air is dry, and so is the vegetation; these are variables that often lead to wildfires. However, there are more ingredients than just these that cause fires. Fire weather is a combination of conditions that set the stage for the rapid spread of wildfires.
Nor’easters are powerful winter storms that can bring hurricane-force wind gusts, coastal flooding, and substantial snowfall to portions of the eastern United States. These low-pressure centers typically develop over the southeastern U.S. before tracking northeastward along the U.S. East Coast.Topics: WeatherOps |
