Empirically derived climate predictability over the extratropical northern hemisphere
climate predictability extratropical northern hemisphere
2009/11/16
A novel application of a technique developed from chaos theory is used in describing seasonal to interannual climate predictability over the Northern Hemisphere (NH). The technique is based on an empi...
A reexamination of methods for evaluating the predictability of the atmosphere
methods for evaluating predictability of the atmosphere
2009/11/13
Pioneering work by Lorenz (1965, 1968, 1969) developed a number of methods for exploring the limits of predictability of the atmosphere. One method uses an integration of a realistic numerical model a...
The role of soil states in medium-range weather predictability
soil states medium-range weather predictability
2009/11/12
Current day operational ensemble weather prediction systems generally rely upon perturbed atmospheric initial states, thereby neglecting the eventual effect on the atmospheric evolution that uncertain...
Long range predictability of atmospheric flows
Long range predictability atmospheric flows
2009/11/12
In the light of recent advances in 2D turbulence, we investigate the long range predictability problem of atmospheric flows. Using 2D Euler equations, we show that the full nonlinearity acting on a la...
The role of boundary and initial conditions for dynamical seasonal predictability
role of boundary initial conditions dynamical seasonal predictability
2009/11/12
The importance of initial state and boundary forcing for atmospheric predictability is explored on global to regional spatial scales and on daily to seasonal time scales. A general circulation model i...
Local predictability in a simple model of atmospheric balance
Local predictability simple model atmospheric balance
2009/11/12
The 2 degree-of-freedom elastic pendulum equations can be considered as the lowest order analogue of interacting low-frequency (slow) Rossby-Haurwitz and high-frequency (fast) gravity waves in the atm...
Long-term predictability of mean daily temperature data
Long-term predictability mean daily temperature data
2009/11/9
We quantify the long-term predictability of global mean daily temperature data by means of the Rényi entropy of second order K2. We are interested in the yearly amplitude fluctuations of the temperatu...
Complexity and predictability of daily precipitation in a semi-arid region:an application to Ceará,Brazil
Complexity predictability daily precipitation semi-arid region
2009/11/9
Complexity and predictability of daily precipitation in a tropical semi-arid region (Ceará State, Brazil) is assessed by applying entropy concepts. Precipitation regimes in that region depend on sever...
Dry and Wet Periods in Eastern China Watersheds: Patterns and Predictability

2008/12/2
Rain gauge observations are the basis for an analysis of the time-space variability of dry and wet pe-riods during the last fifty years in nine Chinese watersheds. The Standardized Precipitation Index...
