An introduction to wavelet analysis in oceanography and meteorology - With application to the dispersion of Yanai waves
TL;DR: In this article, the dispersion of Yanai waves in a reduced gravity equatorial model is studied and the usefulness of the wavelet transform is demonstrated by measuring the group velocity directly over a finite range of wavenumbers by examining the time evolution of the transform.
Journal ArticleDOI
A review of the predictability and prediction of ENSO
Mojib Latif,David L. T. Anderson,Tim P. Barnett,Mark A. Cane,Richard Kleeman,Ants Leetmaa,James J. O'Brien,Anthony Rosati,Edwin K. Schneider +8 more
TL;DR: A hierarchy of El Nino-Southern Oscillation (ENSO) prediction schemes has been developed during the Tropical Ocean-Global Atmosphere (TOGA) program which includes statistical schemes and physical models as mentioned in this paper.

TL;DR: The state of knowledge regarding trends and an understanding of their causes for a specific subset of extreme weather and climate types is presented in this paper for severe convective storms (tornadoes, hailstorms, and severe thunderstorms).
Journal ArticleDOI
A Note on the Vertical Structure of the Eddy Exchange Coefficient in the Planetary Boundary Layer
Journal ArticleDOI
Alternative Solutions to the Classical Vertical Velocity Problem.
TL;DR: In this paper, the kinematic method for determining vertical velocity ω in pressure coordinates is reviewed and an analytical solution to the pressure-differentiated continuity equation is found, which leads to a generalized objective adjustment for divergence estimates which yields improved, physically realistic estimates of ω.
