High-Low Pressure 'Dipole' Froze the East and Baked the West

A new study in Geophysical Research Letters (subs. req'd) takes the warming link to the California drought and the frigid east coast to the next level of understanding. 
The research provides "evidence connecting the amplified wind patterns, consisting of a strong high pressure in the West and a deep low pressure in the East [labeled a 'dipole'], to global warming." Researchers have "uncovered evidence that can trace the amplification of the dipole to human influences."
