KUSA- What have you heard about that will correctly forecast the snow season to come? 9NEWS ran some of the forecasting methods by Colorado's State Climatologist.
Colorado State University is the home of Dr. Nolan Doesken, Colorado's leading authority on statewide weather and climate history. Dr. Doesken has also taught a class about weather folklore and loves to hear about new homespun forecasting techniques.
Folklore: If birds migrate quickly and early a bad winter is ahead.
Doesken: Animals react to ongoing current weather and have no notion of events that may happen two to three months in the future.
Folklore: 90 days after heavy summer fog there will be a huge storm.
Doesken: There are amazing amounts of fog related folklore, I've heard it all over the country, and I don't think any of it holds water but it's very interesting.
Folklore: Here in North Park we've been told that the height that the Miner's Candle plant grows indicates how deep the snow will be in the winter.
Doesken: I've heard this one for years, as well and how tall any plants grows is a function of how good the moisture has been this current growing season. We've found almost no correlation between the current growing season and the upcoming winter.
Folklore: If we have a lot of rain, we'll have a lot of snow.
Doesken: The rains we've had recently have no relationship to snow we have in the winter. In October, there is a little bit of relationship but now not so much.
Dr. Doesken points out that the global circulation patterns influenced by El Nino, La Nina, the North Atlantic oscillation, the Pacific decadal oscillation, the Arctic oscillation, and other large-scale weather phenomena can help forecast a season ahead. However, even those present too many variables to be able to have great accuracy.
