Empirical estimation of the monthly-mean daily temperature range
This is a sequel to a study of the empirical estimation of the annual mean temperature and its range, at any location on land, based on the historical surface climate record. Here the spatial patterns of the daily temperature range (DTR) and its seasonal variation are examined. The DTR is highest in the subtropical deserts and is less at high latitudes, as well as within 30–150 km from an ocean...
متن کاملTemporal Homogenization of Monthly Radiosonde Temperature Data. Part I: Methodology
Historical changes in instrumentation and recording practices have severely compromised the temporal homogeneity of radiosonde data, a crucial issue for the determination of long-term trends. Methods developed to deal with these homogeneity problems have been applied to a near–globally distributed network of 87 stations using monthly temperature data at mandatory pressure levels, covering the p...
متن کاملA complex autoregressive model and application to monthly temperature forecasts
A complex autoregressive model was established based on the mathematic derivation of the least squares for the complex number domain which is referred to as the complex least squares. The model is different from the conventional way that the real number and the imaginary number are separately calculated. An application of this new model shows a better forecast than forecasts from other conventi...
متن کاملThe spatial structure of monthly temperature anomalies over Australia
The use of conventional surface temperature data for the monitoring of climate variability and change presents a major challenge. Meaningful analysis is only possible with consistent station records spanning many years, and networks which are sufficiently dense to sample the variability of interest (Karl et al. 1994; Weber and Madden 1995). In reality, the conventional networks are generally sp...
متن کاملA Statistically Dependent Approach for the Monthly Rainfall Forecastfrom One Point Observations
In this work an adaptive linear filter model in a autoregressive moving average (ARMA) topology for forecasting time series is presented. The time series are composed by observations of the accumulative rainfall every month during several years. The learning rule used to adjust the filter coefficients is mainly based on the gradient-descendent method. In function of the long and short term stoc...
