Nonlinear correlations of daily temperature records over land
We present a near global statistics on the correlation properties of daily temperature records. Data from terrestrial meteorological stations in the Global Daily Climatology Network are analyzed by means of detrended fluctuation analysis. Long-range temporal correlations extending up to several years are detected for each station. In order to reveal nonlinearity, we evaluated the magnitude of d...
متن کاملThe Use of Stomach Temperature Records for the Calculation of Daily Food Intake in Cormorants
We present a new method of measuring the food intake in cormorants based on stomach temperature recordings. Stomach temperature loggers were deployed both in captive and in free-living birds. We examine the accuracy of this method and compare it with the standard methods of evaluating food intake by pellet or stomach content analysis.
متن کاملAppropriateness of correlated first order auto - regressive processes for modeling daily temperature records
The present study investigates linear and volatile (nonlinear) correlations of firstorder autoregressive process with uncorrelated AR (1) and long-range correlated CAR (1) Gaussian innovations as a function of the process parameter (θ). In the light of recent findings [1], we discuss the choice of CAR (1) in modeling daily temperature records. We demonstrate that while CAR (1) is able to captur...
متن کاملDetrended fluctuation analysis of daily temperature records: Geographic dependence over Australia
Daily temperature anomaly records are analyzed (61 for Australia, 18 for Hungary) by means of detrended fluctuation analysis. Positive long range asymptotic correlations extending up to 5-10 years are detected for each case. Contrary to earlier claims, the correlation exponent is not universal for continental stations. Interestingly, the dominant factor is geographic latitude over Australia: th...
متن کاملAn Error Model for Daily Rain Records
Removing outliers from records prior of its use is a major concern in any technical or scientific field. Meteorology is not an exception, and an important effort in devise methods has been made to locate them despite the fact that it has been misconsidered as a purely technical task. The currently applied methods are very crude because they are mostly computerized versions of traditional criter...
