Explicit Formulas involving q-Euler Numbers and Polynomials
In this paper, we deal with q-Euler numbers and q-Bernoulli numbers. We
derive some interesting relations for q-Euler numbers and polynomials by using
their generating function and derivative operator. Also, we show between the
q-Euler numbers and q-Bernoulli numbers via the p-adic q-integral in the p-adic
integer ring.Comment: 9 pages, submitte
A note on q-analogue of Boole polynomials
In this paper, we consider the q-extensions of Boole polynomials. From those
polynomials, we derive some new and interesting properties and identities
related to special polynomials.Comment: 11 page
Barnes-type Daehee polynomials
In this paper, we consider Barnes-type Daehee polynomials of the first kind
and of the second kind. From the properties of Sheffer sequences of these
polynomials arising from umbral calculus, we derive new and interesting
identities.Comment: 34 page
On the effect of the East/Japan Sea SST variability on the North Pacific atmospheric circulation in a regional climate model
Author Posting. © American Geophysical Union, 2014. This article is posted here by permission of American Geophysical Union for personal use, not for redistribution. The definitive version was published in Journal of Geophysical Research: Atmospheres 119 (2014): 418–444, doi:10.1002/2013JD020523.The East/Japan Sea (EJS) is a semi-enclosed marginal sea located in the upstream of the North Pacific storm track, where the leading modes of wintertime interannual variability in sea surface temperature (SST) are characterized by the basin-wide warming-cooling and the northeast-southwest dipole. Processes leading to local and remote atmospheric responses to these SST anomalies are investigated using the Weather Research and Forecast (WRF) model. The atmosphere in direct contact with anomalous diabatic forcing exhibits a linear and symmetric response with respect to the sign, pattern, and magnitude of SST anomalies, producing increased (decreased) wind speed and precipitation response over warm (cold) SSTs. This local response is due to modulation of both the vertical stability of the marine atmospheric boundary layer and the adjustment of sea level pressure, although the latter provides a better explanation of the quadrature relationship between SST and wind speed. The linearity in the local response suggests the importance of fine-scale EJS SSTs to predictability of the regional weather and climate variability. The remote circulation response, in contrast, is strongly nonlinear. An intraseasonal equivalent barotropic ridge emerges in the Gulf of Alaska as a common remote response independent of EJS SST anomalies. This downstream blocking response is reinforced by the enhanced storm track variability east of Japan via transient eddy vorticity flux convergence. Strong nonlinearity in remote response implies that detailed EJS SST patterns may not be critical to this downstream ridge response. Overall, results demonstrate a remarkably far-reaching impact of the EJS SSTs on the atmospheric circulation.H.S. gratefully acknowledges the support
