“…White andCayan, 1998, 2000;White and Allan, 2001). In both latitude domains, SLP anomalies in these modes/waves are observed to be in dynamic equilibrium with anomalous diabatic heating of the troposphere by underlying SST anomalies, while associated surface wind anomalies generate anomalous SST tendencies both overhead and displaced to the east which maintain the modes/waves against dissipation and account for their eastward phase characteristics (White and Peterson, 1996;Qiu and Jin, 1997;Tourre and White, 1997;White and Cayan, 2000;Talley, 1999;Baines and Cai, 2000;White and Allan, 2001).…”

In the extra-tropical Indo-Pacific Ocean, a resultant eastward-travelling Antarctic circumpolar wave (Jacobs and Mitchell, 1996;White and Peterson, 1996) is superimposed on the global standing mode associated with the Pacific South American (PSA) pattern (Cai and Baines, 2001).…”

“…We find these GDR signals associated with corresponding signals observed in spectra of covarying sea-surface temperature (SST) and sea-level pressure (SLP) anomalies over the global ocean (e.g. Allan et al, 1994;Allan, 2000;White and Cayan, 2000;Tourre et al, 2001). Already, annual rainfall over Australia has been shown by White (2000) to be influenced by the interannual global SST/SLP modes/waves evolving in the tropical Indo-Pacific Ocean north of Australia (Yasunari, 1985(Yasunari, , 1989Allan et al, 1994;Tourre and White, 1997;White and Cayan, 2000) and in the extra-tropical Indo-Pacific Ocean east, west, and south of Australia (White and Peterson, 1996;Jacobs and Mitchell, 1996;Peterson and White, 1998).…”

These interannual global SST/SLP modes/waves were found to influence annual rainfall over Australia by affecting an anomalous troposphere moisture flux converging (diverging) over Australia from the surrounding ocean during high (low) annual rainfall (White, 2000).…”

Extreme drought has devastated the flora, fauna, and regional economy in rangeland grazing districts over Australia for 3-5 years duration every 20 to 30 years throughout the 20th century. We investigate the source of drought occurring in five example grazing districts in eastern and central Australia. We find year-to-year variability in grazing district rainfall (GDR) during the summer rainy season (November to March) composed of quasi-biennial, interannual, quasi-decadal, and interdecadal signals from 1900 to 1999. However, the longer period signals dominate, accounting for the interdecadal quasi-periodicity of the drought/flood cycle. We find these GDR signals associated with corresponding global standing modes and travelling waves in covarying sea-surface temperature (SST) and sea-level pressure (SLP) anomalies. These global SST/SLP modes/waves influence the GDR signals by altering the troposphere moisture flux converging onto the grazing districts from regional tropical and extra-tropical oceanic source regions. We construct statistical models to determine whether the evolution of these global SST/SLP modes/waves over the oceanic source regions can hindcast corresponding GDR signals from one year to the next. When these models allow for modulation of the modes/waves, they hindcast ∼1/3 of the variance in the GDR indices at 1 year lead, including the drought episodes. We find drought resulting from the constructive interference of the dry phases of the quasi-decadal and interdecadal global SST/SLP modes/waves, accompanied by a weakening of year-to-year variability associated with either weak quasi-biennial and interannual modes/waves or their destructive interference.

“…These regional QB phenomena are connected by eastwardpropagating SST and SLP waves involving the entire Fig. 1 (White and Allan 2001). Monsoonrelated QB variations are often discussed as the Tropospheric Biennial Oscillation (TBO) (Meehl 1997;Meehl and Arblaster 2002), characterized by year-to-year anomaly reversals, the defining signature of an annually-sampled biennial cycle.…”

A quasi-biennial signal in western US hydroclimate and its global teleconnections

On interannual time scales, quasi-cyclic activity in the troposphere is generally thought to arise from chaotic feedback processes, and therefore to be unpredictable in nature. Here, evidence is presented for periodic 'clockwork' climate behavior, seen as a stable quasi-biennial (QB) oscillation in Western US winter precipitation, estimated at a period of 2.16 ± *0.05 years. In the Western US, the QB precipitation mode has an influence comparable to that of ENSO, with strongest effects observed at central latitudes of the region. The oscillation displays systematic phase-shifting with respect to the annual cycle, signifying a stable, nonseasonal and strongly periodic QB mechanism. The cycle in precipitation results proximally from a meridional standing pressure wave over the North

In the present work, we investigate the interannual variability of the South Indian Countercurrent (SICC), a major and still understudied current of the Indian Ocean circulation. To characterize the interannual variability of the SICC, four different data sets (altimetry, GLORYS, OFAM3, and SODA) are analyzed using multiple tools, which include Singular Spectrum Analysis and wavelet methods. The quasi‐biennial band dominates the SICC low‐frequency variance, with the main peak in the 1.5–1.8 year interval. A secondary peak (2.1–2.5 year) is only found in the western basin. Interannual and decadal‐type modulations of the quasi‐biennial signal are also identified. In addition, limitations of SODA before the 1960s in the SICC region are revealed. Within the quasi‐biennial band, the SICC system presents two main patterns with a multiple jet structure. One pattern is characterized by a robust northern jet, while in the other the central jet is well developed and northern jet is weaker. In both patterns, the southern jet has always a strong signature. When the northern SICC jet is stronger, the northern cell of the subtropical gyre has a triangular shape, with its southern limb having a strong equatorward slant. The quasi‐biennial variability of the SICC is probably related to the Indian Ocean tropical climate modes that are known to have a strong biennial characteristic.
