Editing Lake-effect snow (section)

=== Instability ===
A temperature difference of approximately {{convert|13|°C-change}} between the lake temperature and the height in the atmosphere (about {{convert|1,500|m|ft|abbr=on|disp=or|sigfig=1}} at which barometric pressure measures {{convert|850|mbar|kPa|disp=or|abbr=on}}) provides for absolute instability and allows vigorous heat and moisture transportation vertically. Atmospheric [[lapse rate]] and convective depth are directly affected by both the mesoscale lake environment and the synoptic environment; a deeper convective depth with increasingly steep lapse rates and a suitable moisture level allow for thicker, taller lake-effect precipitation clouds and naturally a much greater precipitation rate.<ref>{{cite web |url=http://www.comet.ucar.edu/class/smfaculty/byrd/sld010.htm |title=Lake Effect Snow: Instability |first=Greg |last=Byrd |date=June 3, 1998 |website=University Corporation for Atmospheric Research |url-status=dead |archive-url=https://web.archive.org/web/20090617013142/http://www.comet.ucar.edu/class/smfaculty/byrd/sld010.htm |archive-date=2009-06-17}}</ref>
