The lowest mean daily maximum temperature over one week periods was the 4th (last) week of January at -1.93=B0 C. = The lowest mean daily maximum temperature was 27 January at -2.88=B0C. The = lowest mean daily minimum temperature over one week periods was also in the 4th (last) week of January at -8.79=B0C and the lowest mean daily minimum temperature was 26 January at -9.99=B0C.=20 The figures averaged over one-week periods are probably more accurate = since they consist of about 100 data points per weekly period compared to the = mean daily temperature that have 15 or fewer data points. These numbers = appear consistent with Peter=92s findings for the Halifax airport. John =20 From: naturens-owner@chebucto.ns.ca = [mailto:naturens-owner@chebucto.ns.ca] On Behalf Of Peter Payzant Sent: February 4, 2013 12:07 To: naturens@chebucto.ns.ca Subject: [NatureNS] The Depths of Winter =20 Hi, all- In deciding when we are really in "the depths of winter", I have been in = the habit of using a rather old set of data for Shearwater airport. This = year, I decided to use more current data for Halifax International, thinking = that it would be more representative. So, today I got the long-term average = daily max and min temps for YHZ, and calculated the daily average = temperatures. It turns out that the coldest days of the winter (averaging -6.45 deg.) = for YHZ are from January 27 through February 2, and that starting February = 3, the temperatures begin to rise again. So I'm happy to report that = starting yesterday, the depths of winter (at least at Halifax International = Airport) are over and the long-term average of temperatures is again trending = upward. Peter Payzant Waverley p.s. the data I used are available here <http://www.climate.weatheroffice.gc.ca/climateData/almanac_e.html?timefr= ame =3D4&Prov=3DNS&StationID=3D6358&hlyRange=3D1961-01-01%7C2012-09-13&Year=3D= 2012&Month=3D2 &Day=3D10> . ------=_NextPart_000_0043_01CE02EB.36EC29A0 Content-Type: text/html; charset="iso-8859-1" Content-Transfer-Encoding: quoted-printable <html xmlns:v=3D"urn:schemas-microsoft-com:vml" = xmlns:o=3D"urn:schemas-microsoft-com:office:office" = xmlns:w=3D"urn:schemas-microsoft-com:office:word" = xmlns:m=3D"http://schemas.microsoft.com/office/2004/12/omml" = xmlns=3D"http://www.w3.org/TR/REC-html40"><head><meta = http-equiv=3DContent-Type content=3D"text/html; = charset=3Diso-8859-1"><meta name=3DGenerator content=3D"Microsoft Word = 14 (filtered medium)"><style><!-- /* Font Definitions */ @font-face {font-family:Calibri; panose-1:2 15 5 2 2 2 4 3 2 4;} @font-face {font-family:Tahoma; panose-1:2 11 6 4 3 5 4 4 2 4;} @font-face {font-family:"MS Shell Dlg"; panose-1:2 11 6 4 2 2 2 2 2 4;} /* Style Definitions */ p.MsoNormal, li.MsoNormal, div.MsoNormal {margin:0cm; margin-bottom:.0001pt; font-size:12.0pt; font-family:"Times New Roman","serif"; color:black;} a:link, span.MsoHyperlink {mso-style-priority:99; color:blue; text-decoration:underline;} a:visited, span.MsoHyperlinkFollowed {mso-style-priority:99; color:purple; text-decoration:underline;} p.MsoAcetate, li.MsoAcetate, div.MsoAcetate {mso-style-priority:99; mso-style-link:"Balloon Text Char"; margin:0cm; margin-bottom:.0001pt; font-size:8.0pt; font-family:"Tahoma","sans-serif"; color:black;} span.EmailStyle17 {mso-style-type:personal-reply; font-family:"Calibri","sans-serif"; color:#1F497D;} span.BalloonTextChar {mso-style-name:"Balloon Text Char"; mso-style-priority:99; mso-style-link:"Balloon Text"; font-family:"Tahoma","sans-serif"; color:black;} .MsoChpDefault {mso-style-type:export-only; font-size:10.0pt;} @page WordSection1 {size:612.0pt 792.0pt; margin:72.0pt 72.0pt 72.0pt 72.0pt;} div.WordSection1 {page:WordSection1;} --></style><!--[if gte mso 9]><xml> <o:shapedefaults v:ext=3D"edit" spidmax=3D"1026" /> </xml><![endif]--><!--[if gte mso 9]><xml> <o:shapelayout v:ext=3D"edit"> <o:idmap v:ext=3D"edit" data=3D"1" /> </o:shapelayout></xml><![endif]--></head><body bgcolor=3Dwhite = lang=3DEN-CA link=3Dblue vlink=3Dpurple><div class=3DWordSection1><p = class=3DMsoNormal><span style=3D'font-size:11.0pt'>Hi Peter and = all,<o:p></o:p></span></p><p class=3DMsoNormal = style=3D'text-autospace:none'><span style=3D'font-size:11.0pt'>I kept 15 = years of weather data at my former home in Doctor’s Brook, = Antigonish Co. from 1998-2012.
