Abstract For developing countries, scarcity of climatic data is the biggest challenge, and model development with limited meteorological input critical importance. In this study, five intelligent hybrid metaheuristic machine learning algorithms, namely additive regression (AR), AR-bagging, AR-random subspace (AR-RSS), AR-M5P, AR-REPTree, were applied to predict monthly mean daily reference evap...
It is shown that the distribution of upper-tropospheric humidity (UTH) in the cloud-free tropics can be simulated with a simple model in which air expelled from moist convective regions is dried by subsidence along its trajectory. The distribution of UTH is analyzed in the tropical eastern Pacific using moisture data retrieved from GOES 6.7 μm observations during September 1992. The analysis ex...
Estimating actual vapor pressure (ea) without relative humidity (RH) data continues to draw research attention. One of the accurate ways estimate ea is through estimation dew point temperature (Tdew) from minimum (Tmin) or mean (Tmean). Two existing methods have been largely used ea. The first method (method I) assumes that Tdew close Tmin. other one II) adjusts Tmin with piecewise correction f...
BACKGROUND The occurrence of eclampsia may be related to season and altitude. METHODS We studied the influence of environmental factors such as range of temperature and relative humidity on the occurrence of eclampsia by collecting data on consecutive cases of eclampsia admitted to the Government Maternity Hospital, Hyderabad, from September 1987 to August 1988. The mean range of temperature ...
OBJECTIVE To evaluate the effect that seasonality has on the occurrence of respiratory symptoms in a Brazilian city with a tropical climate. METHODS This was a cross-sectional study, in which data related to subjects who sought outpatient treatment at a primary health care clinic in the city of Goiânia, Brazil, were correlated with daily meteorological data. Over a one-year period, all the pa...

BACKGROUND Respiratory syncytial virus (RSV) is the leading cause of lower respiratory tract infections in young children globally, with the highest burden in low- and middle-income countries where the association between RSV activity and climate remains unclear. METHODS Monthly laboratory-confirmed RSV cases and associations with climate data were assessed for respiratory surveillance sites ...
The Rajah Brooke's Birdwing, Trogonoptera brookiana, is a large, iconic butterfly that is facing heavy commercial exploitation and habitat loss. Males of some subspecies exhibit puddling behavior. A method of conservation monitoring was developed for subspecies albescens in Ulu Geroh, Peninsular Malaysia, where the males consistently puddle in single-species aggregations at stable geothermal sp...
Blacklegged ticks (Ixodes scapularis Say) are exquisitely sensitive to very cold and dry conditions. For this reason it has long been assumed that climatic differences among locations and within microhabitats have a strong influence on variation in their survival over winter. This assumption, however, rests largely on laboratory exposures and on broad-scale associations between climatic variabl...
