Summit is accessible by air,the Alaska Railroad,and the Anchorage to Fairbanks high- way which is completely paved from Anchorage to Summit. The climate of the area is typical of any interior mountain station at this latitude. Record high temperatures are modified by the altitude.The record lows during Janu- ary and February are representative of the lower elevation,flat interior to the ( ........•..:...northeast.However,the resemblance stops there,with average wintertime low temper- ltures much warmer than the area to the north of the Alaska Range. -,'. The terrain sloping upward from the southwest adds lift to the moist air moving into Alaska from the south causing more rain and snow to occur than at lower elevations. Since the snow melts little in winter,and because strong winds cause continual shifting,it is necessary to place the precipitation gage on a high platform reached by an elevated walkway in order to keep it above the tops of snow drifts and to make it possible to reach the gage without shove1i.ng a,new path each time an observation is made.'

The low annual precipitation is also representative of a continental climate.Mountains surrounding the Gulkana area remove a large portion of the moisture which might otherwise reach the valley,particularly that from off of the Gulf of Alaska which deposits annual amounts in excess of 60 inches on the windward slopes of the Chugach Range.There is no commercial agriculture in the Copper River basin,but with well over half of the annual total precipitation occurring during the four months of June through September,there is adequate moisture for gardening.The average length of the growing season is 78 days.and on the average begins with June 4th and ends August 22nd. Cloud data are available for a short period,but the heaviest precipitation occurrence in su~~er may be indicative of maximum cloudiness occurring during these months. Surface wind directions are prevailing southeasterly during spring,summer and early fall,and froo the north during late fall and winter.Average monthly wind speeds are highest in sum- mer.However,the infrequent occurrences of strong winds in excess of 40 m.p.h.have always been associated with the lighter wind months from October through April. noaa NATIONAL OCEANIC AND ATMOSPHERIC ADMINISTRATION / ENVIRONMENTAL DATA AND /NATIONAL CLIMATIC CENTER INFORMATION SERVICE ASHEVilLE,N,C. ~l I )}1 }-l l,I l 1 l ) Meteorological Data For The Current Year 51<11llon.(ol..LII&hl."l'~K' .---!_!!.~!.::--~~----- hrn.lt-1ilIIUI'"f M,••lh I -;1··.~-_.l-r.--',,> >-€...~~ ~i d ~I •.3-_.__4····-~..if:t;-~l-~iJI.'".li I~'".1 'IS lS~Ii t;o.It Ib.2 liZ 11 "R 29.9 9.~19.1 II!!I IPP lIt1o!ll16 .~H.S !.1I '0 •IV •7.6 1\.2 "b..e.a 27 JU.i1",.li'I ....60 !••61 61 \ JUL 67.11 ..7.2 !i 1.]Ji 21 .uG b).'"lie.J S2.1 I Be 11 stP !.l-.&H.a .2.1/62 I cn J8.~2].ll !1.0 \I 7 '0'Z 1 o'jl ll.1 15.l II "orc -17.60 -]2.2 "'214,9 ...'. -~-.-- Relative if Number of dly.PrecipilaliDll in incl1rl humidity.pct.Wind Average D~gree OilVI -._.---_.-i ,Iillion a,lIe 6S "F FiI'tesl mile I ~.~Temperature Df pressure WaU"equill.lenl Snow.4c.pellet,Reulillnt Sunriae 10 IUnlel mb ~~~~fti !!=u '&Milll;murn Minimum ,----~--~-._-..-j ._-_._-.--_._.I---~.---<~H ~:~1 --- '"'"'"'"~~/1.)Ele\l'. .5 .5 02 08 ••ZO 1;.g is t ~E !~ ~I i:...I,;5 §<.d ~Er ~;..U -£~"i~"I ~19 i~~11 ".~~~.!"f;1 ..-"..Ii i ~~~. .3 1 ~..!....~.ILoe-ltime)H l~~~5 i ~i r ~~;~.5 !"e .0 teet ~~d ~"9 Ii <5 l.g 0 <q ~ln ~!b!m.I.1. <:IN '"«i u .s:q "'-"'>'lil • I!21 bill C 0.1}(1.111 17 lD.Q Sol J!66 '0 U --.------_.-..-•·--3 -·-r -i6--fti 1---2•1--- I.lit 12 0 o.n (I.1S I ••7 2.6 I U I'71 •I n I'lP II I-l'!li-l 0 0.2.0.01 17 10.8 2 ••16 6'IZ 66 •6 0 18 31 7 17 ...0 I ,2'I ,ZO .2 01 60 a 0 0 0 27 0 :•5U C Col •O,lZ zo I ,I o'J!••,0 0 0 "C I 102 2 '.73 0.62 II 0.0 0.0 60 02 .."10 0 7 0 0 0 2 211 I 2.l:l0 a.atl 3D 0.0 0.0 66 .0 65 ..c •0 0 C 2'H3 0 1.67 0.59 II 0.0 0.0 75 52 6'10 0 •0 5 0 I 6 675 0 0.77 0.20 2l ,I J ,..2 ,.7 0 ~a I'0 JO lC-·9 0 0.l:l9 0 ••\•5 ••2.'•U 66 71 •2 0 e·z.0 30 1.a'0 0.10 0.0.27 •••1.0 27 aD 79 61 0 •0 26 Ie • I'2197 Q 0.62 0.27 I]1S.0 7.7 • I 62 57 61 •3 1 SO II 30 DEC JUL oEt I'11329 3 '.57 0.a6 10 146"lI 7.7 IJ 66 59 ••Be 16·21 12.22"60 n&R A"'I::I.a\je~ H.'i 119.0 :a .s E..ueltl JL. 811 5 1- GLJL",,~..I"J(IHil [0 ..U ,lfLO Stand.rd time used:Al.'5KAN Latitude:b:l 0 .19'"Lun9ilude:lit S •27 ••Elevacion C9"DUnd):1512 feel Yelr:1980 Normals,Means,And Extremes --------...-.-_.<>Rlltl.tive ,* Trl"'Ifle,atLJtn F Precipitation in inches h .d'Wind r .Mean number of dlV'Average _Norm.l uml ltv pc;t..-.s nation---r·Drgrer d:VI@.&!C;#C i.~'7.TemperiturelOF pressure I bUefT'lil'1 8.,-65 F Waler equi\l'&lent .,Snow '",_pellets Fanest mil,i IS ...Sunrillll to sunset "'.!I!!~mb.•..~~$"....II ~ii 0 ..:9 MaJ(,Min..---r~r-----·,----+-~-.----'I,----r--,--,.-----,$.,---+---.--.-·$.---j ~'"'"£."~§i - -~5 ~I ~§.~~Ibl Elev.

The valley at this point has a gradual slope -from station elevation to the 1,ODO-foot level at a distance of 15 miles to the west-northwest,and five to seven miles from the northeast through the southwest.Elevation changes in these directions are more rapid beyond this point reaching heights of 4,000 to 6,000 feet at a distance of 25 to 30 miles.Except for isolated peaks (none close)of 2,500 to 4,000 feet there are no significant changes in elevation in the remaining directions.The area immediately surrounding the station is a composite of swampland and slightly higher ground which supports growth of birch and spruce trees. The climate of Talkeetna varies in character between continental and modified maritime. Because of topography the annual precipitation of approximately 28 inches (which in- ,·.,ludes an average annual snowfall-of 100 inches),is about half that measured on the ~ulf of Alaska Coast,and over twice that of the continental regime found in the in- terior.Temperature with a record maximum annual range from minus 48 to 91 is de- finitely continental in nature.Like most areas of Alaska,Talkeetna experiences a "January thaw"with several days of above freezing temperatures.Although ground con- ditions become icy the thaw conditions lower the total snow depth enough to prevent the accumulation of excessive amounts during the winter snow season.The warmest period in summer with readings in the upper 60's and low 70's is from June through mid-July.with cooler weather after mid-July because of the cloudiness and precipitation maximums from late July through September.. Surface winds predominate north or south,depending on the season,because of the orient- ation of the valley.Velocity averages are relatively light. Talkeetna is not a part of the agricultural area of Alaska.Normal moisture distribution results in a maximum rainfall at a time that crops should be maturing and the freeze- free period,which on the average is from mid-June to mid-August,results in too short a growing period. noaa NATIONAL OCEANIC AND ATMOSPHERIC ADMINISTRATION / ENVIRONMENTAL DATA AND /NATIONAL CLIMATIC CENTER INFORMATION SERVICE ASHEVILLE.N.C. r:_h~ '1 l ~~ J '}1 l 1 ;j J l 1 '~•1i Meteorological Data For The Current Year -- Nunlhe,01 daVI i _r:::~~:~i.Temperatllre II F ~~~."~ i~S Muimum Mmimum '~i --------~-a ~Ibl I ~.;:0 t 5 2Q ~..2"~~.·i~;.~'t:I 'u ~ ~i~ii A ii.Ii,~, i::I ~&&l~~q ~...~]~i ~jiii()lfu 0 Ul_...X" T ~1~-~~f-ri ~---.--6---·-if --~~---c~--"it -n--f'i- s ~2 19 8 1 0 D C 12 29 ..•••1 C IZ 11 ~I•2 D D C D ZO 15 D D C r C ,c h 0 n 0 •0 r c I"D Z 0 •0 "< I'0 D 1 ,0 C D I'0 •""0 12 D I?J "0 D 0 2'D 9 :.~2)e S D I "H Jr 2 S 22 .0 ll:I ) :I D 0 30 11 25 21 ~20 .7 n'00 ~1Jllun lu"n:h_1 o\l4So(A lILIiIE£lljA llRPDRI SI.andilldlimeused;"L"$K"~Lillilude;&2"I'"'.Longitude;.!~tr:2~•~~___~__' .__._._ ) T"no.."".·f j T P,.",i"'ion '"'n,h"hU':~~:'I~~''''~Wind It_._~-~......Of9tl!elJ.~.__.~.___r------.............-"---_•._-_••_.•_~a Bilk 65 UF ..'"•A~tl,.l'.ll·'1 (:.aue.mes Wattr eqLlivihml Snow,let pc/jell ~~F"r...Rcwllilnl F4Ilte~1 mile ,:g ~ M"",h -l·--~---~-----r;--~-£.££l ---'-·--1---1-§!§~>_DI go :.:D2 US ''I Z2 c ..,8 ~t.~_~~g ~f:....~~E "!~~"..'SE IJ"~.r!.~.a::1.t::~t~~'8 ~5 ~j I i §I a Il §~~il:I d ;§~il:a ILoco'tlm,1 d 1~~~I oll ~B ~.E i J J"I U~'b :1:..,-"7:-~"i6·LI9-.2~-1·ij-119ci -11-2.,.I.Z'21-'l 21-:ZS-:O u-i,--Tz 70 n _._---~~-r -,0 -·0'..-I~_~- '"".;I •••z ••J ••T 12 -.J7 1117 0 101'D••~I I'••ID.D I eD.5 ,.Z."11..t. •.,II ]".§12."21.1 "It I 30 -all!1273 C Coa9 C.2t!11 10.5 ].It 20"21 15 65 1],2~t,;~It~:::::~I ;:::~~::l ::.:~~;I::~~~~:;~~:~~~~~:~~:~12 ::~~::I ~::~i~ .H,,"tl.l!"b.~,.,.511'2 "iii!],e JJII 0 !..1'J 1.~"lC 0.0 0.0 82 be 7]11 JI..leo Jl..l r.b.~J !O."!t.§i l!!1 2C loll 1 1 202 5.It.be 1.]111 21 0.0'C.O ee.66 17 ~2 17 27 'u(,12.!l1 "&t.e !.:,'l n 11 J!.2"'itS 0 ].'1)0.6S 21 0.0 0,0 91 8!i 66 85.HI"2Q !>lP ~b.21 ~S03 t15.i'66 a 211 :5 569 0 2.U 0.6].....U 0.0 0.0 861 III alii 22 l"t QLl "2.$:'9.0 U.8 ~i 1 9 31 en C'2.1"0.67 7"'8 It.)1.7 •eli 83 fo 82 :1 :J]21 ""(,~~2.~'la.!2$.1 It]..-]JC 1112 "I.DB DoH U-l1 15.5 ".9 13 1'9 81 7]78 If!1b 211 Ll("'.l1-12.~~...2 33[~I ~)1 U 21qlt 0 0.56 D.]t']I 1.1 11.8 29-]0 611 6!i U 66 I 2:C~• I JI,:l..O£C JUN r[p J,....

The Alaska Mountain Range lies in a long arc from southwest,through northwest,to northeast,approximately 100 miles distant from Anchorage.During the winter,this Range is an effective barrier to the influx of very cold air from the north side of the Range.Extreme cold winter weather,associated with a high pressure system over interior Alaska,may lead to a succession of clear days in Anchorage,with temperatures dropping to -15°to _30°,as con- trasted to the _50 0 and even _69 0 readings in the interior.There are some factors,however,which tend to offset the sheltering effect of this mountain barrier.Chief among these is cold air entrapment in various suburban areas during periods of light winds.This results occasionally in temperatures on the outskirts of Anchorage as much as 15°to 20°colder than observed at the official observation sites. The four seasons are well marked in the Anchorage area,but in length,and in some major characteristics,they differ considerably from the usually accepted standards in middle latitudes. Winter is considered to be the period during which the ponds,streams,and lakes are frozen;this normally extends ,from mid-October to mid-April.The shortest day of the year has 5 hours and 28 mjnutes of possible sunshine. ;':'eriods of clear,cold weather normally alternate with cloudy,mild weather during the Anchorage winter.The 'clear,cold weather is frequently accompanied by significant fog because of the important low-level moisture source provided by the arms of Cook Inlet which surround the area on three sides;while considerable floating ice is prevalent,the high tides maintain some open water throughout the winter.Visibilities of 1/2 mile,or less,occur about 5 percent of the time during December and January,and most of these low visibilities are associated with fog.Snow visibilities generally range from 1 to 3 miles though heavier snowfalls will,of course,restrict visi- bilities to less than a mile on a few occasions.The first measurable snow occurs,on the average,on October 15, but has been as early as September 20;latest measurable snow in the spring averages April 14,but has been as late as May 6.Snow occurs on 20 to 25 percent of the midwinter days,and most.of the snow falls in relatively small daily amounts,with only 2 percent of.the midwinter days haVing more than 4 incbes.The heavier snows occur in conjunction with vigorous stor~centers moving northward aCT'oss south-central Alaska.Normally,the depth of snowfall on the ground does not exceed 15 inches.Strong,gusty,north winds which occur,on the average,once or twice during the winter will,under favorable snow conditions,cause drifting and packing of snow cover.Although normally an area of light winds,strong "Northers"at Anchorage occasionally result from the rapid deepening of storms in the nearby Gulf of Alaska at a time when the interior is covered by an extensive mass of quite cold air. Spring is the period immediately following the famed Alaska "Break-up."This season is characterized by warm, pleasant days and chilly nights;the mean temperature rises rapidly;precipitation amounts are exceedingly small. Summer comprises the period from June through early September,and is,in reality,two seasons of about equal length,the first of which is dry,the second wet.At the time of the summer solstice,possible sunshine in Anch- orage amounts to almost 19~1/2 hours,and the sound of singing birds and pounding hammers is nearly as common at midnight as at noon.About the middle of July average cloudiness increases markedly,and the remainder of the summer usually accounts for about 40 percent of the annual precipitation. Autumn is brief in Anchorage,beginning shortly before mid-September and lasting until mid-October.The frequency of cloudy days and precipitation drops sharply in early October.Measurable amounts of snow are rare in September, but substantial snowfalls sometimes reaching 10 or 12 inches occasionally occur in mid-October.Some of the stronger southerly winds,a few with damaging effects,occur in the late summer or fall;these are post-frontal winds follow- ing the movement of a storm from the southern Bering Sea or Brist~l Bay,northeastward across the Alaskan interior. Somewhat less frequent,but more damaging,are the southeasterly "Chugach"winds which are funneled down the creek canyons on the northwestern slopes of the Chugach mountains east of the city;gusts estimated at 80 to 100 mph have caused considerable damage to roofs,power lines and trailers on a few occasions.The growing season in Anchorage ..)verages 124 days,with the mean daily temperature above freezing from April 8 to October 23.May 15 is the average ~Sate for the last occurrence in spring of a temperature as low as 32°,while September 16 is the average first date with 32°in the fall.The latest date with 32 0 in spring has been June 6,and the earliest with 32°in the fall August 14. noaa NATIONAL OCEANIC AND ATMOSPHERIC ADMINISTRATION / ENVIRONMENTAL DATA AND /NATIONAL CLIMATIC CENTER INFORMATIOI'!SERViCE ASHEVILLE,N.C. r-7C ':..cc ~"':~~~': 0000"",,,,"00- 0000'00- ~~~o-~o- OOOOe""" a:--:~ro:-:~ ....OO_:r\l1o- Qo-OOOO 00-0000 swt JO ~I!W Yo.:::: Al!l~rs!A '60j..AAnH cc ;;QQCCO~ ~",:"":~~a: "'Oo~,g,..<o CQaO'O'Cl ~2~1Jo~~ /lIlOloiQ I'"0 0 c en'_.o[ ~.....OlaqJ.."OO'IJoNC~pue"lCiMNN -'~H-----:""~1--I.------ ~MOlaq I'('~CCCO uoo-::~;!.1 \-.....:.__.::0:£.:.-+(N_-_-_ ~.o:amql ~~Coo ,...u C e1 ....C P n 00 puo .06 I c....- -... ..
