How often and for how long are doors kept open? Actual Evapotranspiration (AET) is the evaporative water loss given the actual water availability at a site, and therefore represents the biologically usable energy and water in the environment. Downscaled modeled variable outputs are monthly values at 60 m resolution. Inland, often less than 10 inches (254 mm) falls a year and on the North Slope as little as 4 inches (100 mm) of rainfall equivalent and 30 inches (0.76 m) of snow is typical, but what snow falls during the winter tends to stay throughout the season. This is due in large part to its proximity to the coast. See Morrison et al., 2019 for data acquisition and modeling details. I've used quantile regression in a few contexts but this discussion is helpful.I'm curious as to how quickly the confidence intervals widen as you run the regression farther out in the tails; for example, presumably tercile regression estimates are quite stable but decile estimates much less so (e.g. Barrow weather averages and climate Barrow, Alaska. Climate Normals are three-decade averages of climatological variables including temperature and precipitation. The sun does not rise at all during some weeks in the winter, and is out for 24 hours during some weeks in the summer. The variables, their units, and descriptions are listed in Table 1. From this baseline, monthly averages for total surface radiation, rain, snow, potential evapotranspiration, actual evapotranspiration, and water deficit were also modeled. Lawrence, R.B. "I suggest a new measure that devolves from statistics...BTU's of fuel consumed to heat a dwelling per winter by location. These data are available through the Oak Ridge National Laboratory (ORNL) Distributed Active Monthly Climate Normals for Alaska Stations Daily Climate Normals for Alaska Stations The normals products you'll find here represent average conditions over the most recent climate normal period (1971 - 2000). Much of the southern parts are temperate rainforest. Each month is identified by number (1 to 12) and time period is either '1975-2005' or 'lgm' for the Last Glacial Maximum. The annual averages are coarser-resolution upsampled versions of the 60 m resolution monthly average data. Then annual averages were aggregated to coarser resolutions of 120m, 240m, 800m, 1km, 2km, 3km, 4km, 5km, 10km and 12km. Neale, P.J. The DEM was resampled and reprojected to Alaska Albers Equal Area Conic, ensuring grid cells of exactly 60 m.  From this dataset, slope, aspect, and the topographic convergence index (TCI) for Alaska were calculated. Climate Normals for Last Glacial Maximum and Modern (1975-2005), Alaska. You bet Gary, dollars are where the rubber meets the road, so to speak. What is the target temperature for indoor heat. On average, Anchorage receives 16 inches (410 mm) of precipitation a year, with around 75 inches (1.91 m) of snow. The northern coast of the Gulf of Alaska receives up to 150 inches (3,810.0 mm) of precipitation annually. Potential Evapotranspiration (PET) reflects plants use of energy and water to grow and reproduce, therefore the primary effects of climate on plants is regulated by the interactions of energy and water. Yang, and M.H. Annual average files for each variable (8 variables) for two time periods are provided at 11 different resolutions. 1. However, despite 24 hours of sunshine in the summertime, the average low temperature is barely above freezing in Utqiagvik in July, at 34 °F (1.1 °C) and snow may fall any month of the year. Coarse scale (1°) general circulation model (GCM) climate grids were collected from the NCAR CCSM4 for near surface (2 m) Tmin, Tmax, Tave, precipitation, short wave radiation (Icloud) and wind (U, V) (Gent et al., 2011, Kluzek, 2011). 30-year annual average maximum temperature for Alaska at 60-m resolution for (a) the last glacial maximum period ~18,000 years ago and (b) the modern period 1975-2005. It is a subarctic climate (Köppen Dfc) due to its short, cool summers. This product is produced once every 10 years. The research could help clarify the effect of climate grid resolution on estimations of novel and disappeared climates. Anchorage gets a thunderstorm every few years. The models were evaluated by computing the Pearson's correlation, root-mean square error (RMSE), and percent bias for each model based on observed vs. predicted temperature/precipitation values. In a state this size, our weather can vary dramatically by region and season. These products were obtained from the National Climatic Data Center. One of the things that interests me is how people adjust to a changing climate. (2016). [2] Thunderstorms are fairly rare in most of Alaska, but do occur in the interior in the summer with some frequency and may cause wildfires. Downscaling Input Data: [5][6][7][8] The lowest Alaska temperature is −80 °F (−62.2 °C) in Prospect Creek on January 23, 1971,[5][6] 1 °F (0.6 °C) above the lowest temperature recorded in continental North America (in Snag, Yukon, Canada). Alaska has always been known as a land of extremes when it comes to weather and climate. The northern side of the Seward Peninsula is technically a desert with less than 10 inches (254 mm) of precipitation annually, while some locations between Dillingham and Bethel average around 100 inches (2,540 mm) of precipitation. The temperature is somewhat moderate considering how far north the area is. Winter 2016-17 was certainly colder than the previous three in Fairbanks-land (yeah). See Morrison et al., 2019. Alaska's Climate Home » Planning your trip to Alaska. Spatial Scale Affects Novel and Disappeared Climate Change Projections in Alaska. AET and water deficit were calculated using a snow hydrology model that models additional water and energy parameters that influence available water at a site. Hi, Rick T. here. 2019. Average monthly precipitation is generally highest in the autumn months, especially October, and lowest in May or June. Objective Comments and Analysis - All Science, No Politics, The Fairbanks Flood of 1967: The Rainfall. Very interesting, Rick. Some of the hottest and coldest temperatures in Alaska occur around the area near Fairbanks. If a map of Alaska was put over a map of the Lower 48 states, we’d stretch from Savannah, Georgia to Los Angeles, and from the Texas Panhandle to the top of North Dakota. Owing to the rain shadow of the coastal mountains, south-central Alaska does not get nearly as much rain as the southeast of Alaska, though it does get more snow with up to 300 inches (7.62 m) at Valdez and much more in the mountains. Contact for Data Center Access Information: Aggarwal, C.C., (2017). These climate normal data products were used to evaluate changes in climate across Alaska over the two time periods and to assess how results might depend on the spatial resolution of the input data products. Perhaps at elevation above the valley inversion it was not? [10] Across western sections of the state, the northern side of the Seward Peninsula is a desert with less than 10 inches (250 mm) of precipitation annually, while some locations between Dillingham and Bethel average around 100 inches (2,540 mm) of precipitation.[11]. The climate in Juneau and the southeast panhandle is a mid-latitude oceanic climate (similar to Scotland, or Haida Gwaii), (Köppen Cfb) in the southern sections and a subarctic oceanic climate (Köppen Cfc) in the northern parts.
