Summary
[edit]DescriptionFires in Alaska (MODIS 2019-07-11).jpg |
English: An upper-level ridge of high pressure that slid over Alaska in June 2019 unleashed a heat wave of astonishing intensity. With temperatures soaring into the 80s and even 90s (Fahrenheit) in some parts of Alaska, several all-time and daily temperature records fell.
Anchorage, Kenai, and King Salmon broke all-time records on July 4, 2019. In Anchorage, the record was not just broken; it was obliterated. The city reached 90°F (32°C) on Independence Day; the previous record was 85°F (29°C) on June 14, 1969. Daily temperature records have been kept for Anchorage since 1952. This heat has also been unusual for how long it has lingered. Anchorage faced six consecutive days where temperatures exceeded 80 degrees, the longest stretch on record. The city broke daily high-temperature records eight times between June 23 and July 8. The normal daily high for Anchorage in July is 17°C (62°F). High temperatures have continued through July 10, with a recording of 91°F (32.8°C) recorded at Bethel on that date. Alaska is expected to continue to swelter for several more days, with a potential break in the heat at the end of the week. In many parts of Alaska, the heat has been accompanied by raging wildfires and thick smoke. Clusters of lightning-triggered wildfires have been burning around Fairbanks since June 21, 2019. A second cluster began burning south of the Koyukuk Wilderness on July 5. Fires spread more quickly in hot weather because the amount of heat needed to warm fuels to the ignition point is lower. Fires generally burn with the most intensity in the afternoon, when temperatures are typically warmest. The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite captured a true-color image of thick wildfire smoke swirling over the state on July 7, 2019. The next day, meteorologists in Fairbanks reported visibility had dropped to less than one mile due to smoke, and air quality sensors in the city reported skyrocketing levels of particulates in the air. As of July 9, there were 38 large fires burning in Alaska. They had consumed a total of 697,000 acres, about 52 percent of all acreage burned in the United States in 2019, according to the National Interagency Fire Center. The largest Alaskan fire, Hess Creek, was burning through forests of black spruce and mixed hardwoods (birch, aspen, and white spruce) north of Fairbanks. It had charred 172,548 acres (69,827 hectares) as of July 9, making it the largest fire in the United States so far in 2019. |
