SINGULARITIES IN DAILY TEMPERATURES
Journal of Meteorology, 1959Abstract The means of daily maximum temperatures using twenty years of record are obtained. The average of these means over n consecutive calendar days is used as a predictor of the daily maximum temperature one and more years in advance. Data from ten stations in the United States for the period 1905 to 1957 are analyzed in this fashion and a series ...

Homogenization of Daily Temperature Data
Journal of Climate, 2017Abstract This paper develops a method for homogenizing daily temperature series. While daily temperatures are statistically more complex than annual or monthly temperatures, techniques and computational methods have been accumulating that can now model and analyze all salient statistical characteristics of daily temperature series.

Modeling the Daily Average Temperature
2012The purpose of this chapter is to develop a model that accurately describes the dynamics of the DAT. The statistical properties of the DATS will be examined in order to propose a process that exhibits the same behavior. Our model will be evaluated and compared in-sample and out-of-sample in seven locations against models previously proposed in ...

A temperature calculation model: The case of minimum daily temperature
Atmospheric Environment. Part A. General Topics, 1993Abstract In the present work a model based on the linear relationship between variations in the relative humidity of the air and those of temperature is applied to calculate minimum daily temperatures as a function of the maximum humidity value and the value measured in a thermometer screen at 1800 UTC of the previous day.

Daily temperature extremes as an indicator of high temperature stress
Australian Journal of Soil Research, 1991Theory outlining a general relationship between stress experienced by an organism exposed to supra-optimal temperatures and daily temperature extremes is discussed. It is shown that useful nomograms relating Tmax, Tmin, Tcritical, and high temperature stress can be developed and that these nomograms are not particularly sensitive to changes in ...

Daily temperature variations on Mars
Journal of Geophysical Research: Solid Earth, 1982The Viking infrared thermal mapper (IRTM) has measured the infrared brightness temperature of Mars for more than a full Martian year. The daily variation of the 20‐μm brightness temperature can be predicted to within ±5 K for most of the Martian surface during any season if the radiometric albedo and the thermal inertia of the model are allowed to ...

Temperature Effects on the Winter Daily Electric Load
Journal of Applied Meteorology, 1982Abstract Here we describe the relationship between average daily temperature and winter-daily electric load, as ascertained on the largest electric district in Italy. In particular, it is shown that a sudden 6°C temperature decrease (not a rare event) raises the load by ∼5%. Several aspects of users' behavior before temperature changes are also pointed

The relation between daily activities and scrotal temperature
Reproductive Toxicology, 2002Normal sperm production depends on a testicular temperature below body temperature, but the thermogenic effects of daily life activities are not well known. We described the association between scrotal temperature and daily activities in 101 males using a non-invasive method for measuring scrotal temperature.

DAILY TEMPERATURE OPTIMISATION IN GREENHOUSE BY REINFORCEMENT LEARNING
IFAC Proceedings Volumes, 2005Abstract The goal of this study is to show the usefulness of reinforcement learning (RL) to solve a common greenhouse climate optimisation problem. The problem is to minimise the daily heating cost while achieving simultaneously two agronomic goals, namely maintaining a good crop growth and an appropriate development rate.

Effect of suprachiasmatic ablation on the daily temperature rhythm
Neuroscience Letters, 1977Abstract To evaluate the role of the suprachiasmatic nuclei (SCN) in maintenance of body temperature, the rectal temperature of 5 SCN ablated and 8 intact female rats were measured every 4 h over a 48-h period (80 days postsurgery). Intact as well as SCN ablated rats showed significant 24-h fluctuations in body temperature.
