متن کاملObservational evidence of European summer weather patterns predictable from spring
Forecasts of summer weather patterns months in advance would be of great value for a wide range of applications. However, seasonal dynamical model forecasts for European summers have very little skill, particularly for rainfall. It has not been clear whether this low skill reflects inherent unpredictability of summer weather or, alternatively, is a consequence of weaknesses in current forecast ...
متن کاملIs genetic evolution predictable?
Ever since the integration of Mendelian genetics into evolutionary biology in the early 20th century, evolutionary geneticists have for the most part treated genes and mutations as generic entities. However, recent observations indicate that all genes are not equal in the eyes of evolution. Evolutionarily relevant mutations tend to accumulate in hotspot genes and at specific positions within ge...
متن کاملHow Predictable Is
JULY 2003 AMERICAN METEOROLOGICAL SOCIETY | A recent analysis of 12 statistical and dynamical models used for El Niño predictions finds that at the long (1–2 yr) and even medium (6–11 months) ranges there were “no models that provided useful and skillful forecasts for the entirety of the 1997/98 El Niño” (Landsea and Knaff 2000). Most of the models were wrong in predicting the timing of the ons...
