  1. As we enter the new year and new decade, time to make a new thread. Happy New Year!
  2. Meteorological spring starts a day late this year. Astronomical spring never does. Welcome to March. Roller coaster weather is not too far off.
  3. Rough draft of a possible improved climate classification system...partially adapted from M. Fantamon. All temperatures reflect the mean (average of diurnal high and low). When considering a climate classification, choose the best fit if multiple classifications exist. Temperature conditional, precipitation conditional If bold the condition applies to the entire climate group (ie tropical climates). Equatorial (A) coldest month > 22cannual amplitude <= 5cannual precip >= 2000 mm, wettest month less than 2x wetter than driest month equatorial rainforest (Ar)annual precip >= 1000
  4. Wow! 2018 just flew by just like that and only 6 days until 2019. Hopefully we see a wetter January-April period with plenty of rain and snow up in the mountains.
  5. Time for the summer forecast contest, as we hope to see summer arrive some time this year in what's been the coolest and wettest May in decades for California and pretty much all of the Southwest Predict the monthly anomalies for June, July, and August, at these locations: You've got until Monday, June 3 to make your guesses SEA (Seattle, WA) OLM (Olympia, WA) PDX (Portland, OR) CQT (Downtown LA) DEN (Denver, CO) DCA (Washington D.C.)
  6. Looking at climate through the lens of degree days (base 65 F US, 64 F/18 C INTL) Cooling degree days occur any time the mean temperature of the day is more than 65 F/18C. Heating degree days occur any time the mean temperature of the day is less than 65 F/18C. A good way to measure climates is to look at the mean HDDs and CDDs during a typical year. We can also sum the two to get an idea of how relatively comfortable a climate is, and how much energy is required in that climate to heat and cool a building through a typical year. Hottest locations in the world by CDD: Mecca, Saudi Arabia
  7. Olympia averages 50.00" of precipitation a year while Seattle averages 37.49" a year. What causes the differences in precipitation amounts between Olympia and Seattle?
  8. Hi Everyone. Here is a place where we can discuss the latest weather blogs from our favourite Pacific Northwest meteorologists. We can also create a big aggregate list of our favourite blog sources, so chime in if you find a worthy, undiscovered weather blogger. Cliff Mass' Latest post showed a beautiful NAEFS Diagram for a prediction of the Super Bowl. Great informative post about ensemble forecasting highlighting just how far we can accurately predict weather. EDIT: The Master Blog List: Brett Anderson: Canadian Accuweather Blog Capital Weather Gang: Washington D.C. Cliff Mass: Sea
  9. Hey! I am new here so I thought I would introduce myself I am Remy Mermelstein, in 10th grade at Irvington High School in NY just north of NYC. I have always been interested in weather, and did many reports on different weather topics back in elementary school. Back at the end of 8th grade I made my own Facebook Blog where I post forecasts almost every day, and other weather discussions, homemade maps and model data, the FB page is called Weather Or Not in the Rivertowns with Remy Mermelstein, it can be found at this link: https://www.facebook.com/remyweatherchannel Halfway through fres
