An Extended Pacific–North American Index from Upper-Air Historical Data Back to 1922

Autor: Tracy Ewen, Jeffrey L. Annis, Stefan Brönnimann

Publikováno v: Journal of Climate. 21:1295-1308

This paper presents a reconstruction of a Pacific–North America (PNA) index from historical upper-level data for the period 1922–47. The data have been compiled from a number of sources and cover the Pacific–North American sector relatively wel

Climatic Influences on Midwest Drought during the Twentieth Century

Autor: Warren B. White, Alexander Gershunov, Jeffrey L. Annis

Publikováno v: Journal of Climate. 21:517-531

The Dustbowl Era drought in the 1930s was the principal Midwest drought of the twentieth century, occurring primarily in late spring–summer [April–August (AMJJA)] when >70% of annual rainfall normally occurred. Another major Midwest drought occur

Forecasting Australian drought using Southern Hemisphere modes of sea-surface temperature variability

Autor: Warren B. White, Jozef Syktus, Jeffrey L. Annis, Greg McKeon, Alexander Gershunov

Publikováno v: International Journal of Climatology. 24:1911-1927

Drought of 3 to 7 years’ duration has devastated the flora, fauna, and regional economies in rangeland grazing districts over eastern and central Australia every 15 to 25 years throughout the 20th century, in some cases degrading the land beyond re

Coupling of Extratropical Mesoscale Eddies in the Ocean to Westerly Winds in the Atmospheric Boundary Layer

Autor: Warren B. White, Jeffrey L. Annis

Publikováno v: Journal of Physical Oceanography. 33:1095-1107

The sea surface temperature (SST) signature in mesoscale eddies in the western boundary current extensions around the globe and in the Antarctic Circumpolar Current are found to alter the surface stress associated with background westerly winds, prod

Reconstructing the quasi-biennial oscillation back to the early 1900s

Autor: Stefan Brönnimann, Jeffrey L. Annis, Phil D. Jones, Christian Vogler

Publikováno v: Geophysical Research Letters. 34

[1] The quasi-biennial oscillation (QBO) is important for understanding the dynamical and chemical variability of the global stratosphere. Currently available wind data from the equatorial stratosphere extend back to 1953. Here we present reconstruct

Hand-written or printed manuscript data are an important source for paleo-climatological studies, but bringing them into a suitable format can be a time consuming adventure with uncertain success. Before digitising such data (e.g., in the context a s

Influence of the Antarctic Circumpolar Wave on El Niño and its multidecadal changes from 1950 to 2001

Autor: Jeffrey L. Annis, Warren B. White

Publikováno v: Journal of Geophysical Research. 109

[1] The slow eastward phase propagation of covarying sea surface temperature (SST) and sea level pressure (SLP) anomalies in the Antarctic Circumpolar Wave (ACW) persisted in the midlatitude Southern Ocean from 1950 to 2001. Its northern extent reach
