River channel conveyance capacity adjusts to modes of climate variability

Principal nonlinear dynamical modes of climate variability

We suggest a new nonlinear expansion of space-distributed observational time series. The expansion allows constructing principal nonlinear manifolds holding essential part of observed variability. It yields low-dimensional hidden time series interpreted as internal modes driving observed multivariate dynamics as well as their mapping to a geographic grid. Bayesian optimality is used for selecti...

Climate variability and Ross River virus transmission.

OBJECTIVES (1) To examine the feasibility to link climate data with monthly incidence of Ross River virus (RRv). (2) To assess the impact of climate variability on the RRv transmission. DESIGN An ecological time series analysis was performed on the data collected between 1985 to 1996 in Queensland, Australia. METHODS Information on the notified RRv cases was obtained from the Queensland Dep...

Street Storm Water Conveyance Capacity

The street hydraulic capacity to convey storm water is dictated by the street gutter geometry and hydraulic characteristics. With the consideration of traffic safety, the street hydraulic conveyance capacity is also subject to a reduction defined by the water velocity and flow depth in the street gutter. In this study, the street hydraulic equation is re-arranged to demonstrate that the water v...

Reducing Uncertainty in River Flood Conveyance

Projection of Climate Change onto Modes of Atmospheric Variability

Two possible interpretations of forced climate change view it as projecting, either linearly or nonlinearly, onto the dominant modes of variability of the climate system. An evaluation of these two interpretations is performed using annual mean sea level pressure (SLP) and surface air temperature (SAT) fields obtained from integrations of the Geophysical Fluid Dynamics Laboratory coupled genera...
