1. 1) This map of Alaska has been divided into four major regions: the southern, or Gulf  of Alaska, region, the continental, or interior, region in the center, the Bering Sea  region to the west, and the Artic region to the north. The delineation of these regions  is based on information found pertaining to ecoregions in the state, (see http://www-eros-afo.wr.usgs.gov/ecoreg/ecoreg/ecoremap.html).  In the four regions specified,  various ecoregions, holding similar characteristics have been joined. The regions are  similar, as well, to those defined by Hartman and Johnson in The Environmental  Atlas of Alaska, (University of Alaska, 1984, Fairbanks). The regions are, in  general, thus described:

• Southern Alaska: small temp variations, high humidity, high precipitation, and high cloud and fog frequency.
• Bering region: transitional--more pronounced temp variations throughout the  day and year, lower precipitation and humidity.
• Continental: high diurnal and annual temp variations, low precipitation, and low cloudiness.
• Arctic: less temp variation than continental, precipitation is light--the summer may see some marine influence, but not much at all is seen in the winter, when the  Arctic is frozen

1. 2) http://fermi.jhuapl.edu/states/maps1/ak.gif Topographic map of Alaska. Make notice comparing this to the regional map, that the Southern region is defined to the north by  the ranges of mountains, (creating a transition between the maritime climate of the  south and the continental climate of the interior)

1. 3) http://climate.oA.alaska.edu/AKCityClimo/ALL_Rec.html Alaska city climate  trends--30 year running average temperature comparisons: This graph illustrates the  trend of decreasing temperatures as one moves north through the state, (Juneau being  the southern-most city on the graph and Barrow the northern-most).

1. 4) http://climate.gi.alaska.edu/AKCityClimo/ALL_pcpn.html The THIRD graph down  at this sight illustrates the trend of decreasing precipitation as one moves along a  gradient moving north through Alaska, with the exception in the mid-summer months  with Nome receiving more precipitation than Anchorage, because of its location on  the Bering Sea.

1. 5) http://climate.gi.alaska.edu/AKCityClimo/ALL_sf.html The THIRD graph down  shows the precipitation at the same six cities as the last graph. It illustrates the  significant difference in daily amount snowfall between Juneau (in the Southern  region) and Barrow, (in the Arctic region). The Southern region receives more  snowfall.

1. 6) Southern Alaska chart of average temp and precipitation. Temp is in deees  Fahrenheit and the average precipitations, snowfalls, and depths are in inches. The  small temperature ranges, moderate temperatures, and high precipitation and  snowfall, with relatively low average depth are all indicative of a moderate maritime  climate.

1. 7)Interior Alaska chart of mean temperatures and precipitations at various times of the year. The great annual range in temperature is characteristic of this region where the winter are colder and the summers are warmer.
