POWERS Julian

The Unitary Executive offers a powerful case for the historical pedigree of the unitary executive theory. Offering an account of presidential practice stemming from George Washington to George W. Bush, the book seeks to ground unitary executive theory with exhaustive historical evidence. Although the authors do not purport to present a history of the presidency, they do provide important and co...

Statement Julian

My mathematical research interests are in number theory and algebraic geometry. My thesis work concerns the arithmetic of a family of rational numbers known as multiple harmonic sums, which are truncated approximations of multiple zeta values. I explore new structures underlying relations involving multiple harmonic sums, p-adic L-values, Bernoulli numbers, and binomial coefficients. This is us...

NOTES AND CORRESPONDENCE On the Relationship between the Streamfunction and Velocity Potential of the Madden–Julian Oscillation

The streamfunction and velocity potential variances associated with the Madden–Julian oscillation are explained substantially by their zonal wavenumber-1 components, which are used to measure quantitatively the phase relationship between the two variables. There exists a quarter-cycle phase difference between them. A simplified streamfunction budget equation was used to demonstrate analytically...

NOTES AND CORRESPONDENCE On Wind, Convection, and SST Variations in the Northeastern Tropical Pacific Associated with the Madden–Julian Oscillation*

Lagged maximum covariance analysis (LMCA) is used to examine the intraseasonal variability of zonal wind, sea surface temperature (SST), and outgoing longwave radiation (OLR) in the northeastern tropical Pacific Ocean during Northern Hemisphere summertime. The analysis shows a strong temporal asymmetry in that wind and convection anomalies lead to SST anomalies, but SST anomalies are not follow...
