Another product to keep an eye on is the Climate Prediction Center CFS Forecast of
Seasonal Climate Anomalies.
Not exact matches
While the local,
seasonal climate forcing by the Milankovitch cycles is large (of the order 30 W / m2), the net forcing provided by Milankovitch is close to zero in the global mean, requiring other radiative terms (like albedo or greenhouse gas
anomalies) to force global - mean temperature change.
If a particular
seasonal anomaly appears to be related to El Nino, can we conclude that
climate change played no role at all?
3) Snow cover: The radiative and thermal properties of widespread snow cover
anomalies have the potential to modulate local and remote
climate over monthly to
seasonal time scales
The use of
anomalies avoids this
seasonal / regional variation, because when the
climate isn't changing, neither will be the
anomalies except for local noise.
