to analysis the mechanisms of blocking high effects on heavy precipitations in northwest of iran, we selected a short period of heavy precipitation (25-28 october 2008). in this case, weather maps such as mean of sea level pressure, 850-hpa and 500-hpa geopotential height levels were assessed and analyzed for the whole period. the position and movement of the atmospheric systems such as cyclone...

Recent increases in regional wildfire activity have been linked to climate change. Here, we analyse trends observed global extreme fire weather and their meteorological drivers from 1979 2020 using the ERA5 reanalysis. Trends annual (95th percentile) values of index (FWI95), initial spread (ISI95) vapour pressure deficit (VPD95) varied regionally, with mean 14, 12 12%, respectively. Significant...

POI recommender systems for location-based social network services, such as Foursquare or Yelp, have gained tremendous popularity in the past few years. Much work has been dedicated into improving recommendation services in such systems by integrating di↵erent features that are assumed to have an impact on people’s preferences for POIs, such as time and geolocation. Yet, little attention has be...

This paper presents some installation and data analysis issues from an ongoing urban air temperature and humidity measurement campaign in Hangzhou and Ningbo, China. The location of the measurement sites, the positioning of the sensors and the harsh conditions in an urban environment can result in missing values and observations that are unrepresentative of the local urban microclimate. Missing...

Twelve months of automated hourly pedestrian counts in downtown Montpelier, Vermont (pop. 8,035) were analyzed along with weather data (temperature, relative humidity, precipitation, and wind) to determine the factors affecting count variability. The study is unique in that a large amount of data in a single location was collected in a locale with an extreme range of weather conditions. Results...

Weather condition is one of the much effective factors in the principle of architecture and urbanization. So in this research long-term trend of effective climate elements in architecture of Darab city including mean of minimum temperature, temperature mean, mean of maximum temperature, minimum relative humidity, maximum relative humidity, relative humidity mean, wind speed and sun hours in mon...

The morbidity and mortality of hand, foot and mouth disease (HFMD) are increasing in Beijing, China. Previous studies have indicated an association between incidents of HFMD and weather factors. However, the seasonal influence of these factors on the disease is not yet understood, and their relationship with the enterovirus 71 (EV71) and Coxsackie virus A16 (CV-A16) viruses are not well documen...

We present here the 2001–2004 results of observational field studies aimed at quantifying tropical timberline climate and radial increment of Pinus hartwegii Lindl. trees on Nevado de Colima, in the middle of the North American Monsoon region. An automated weather station was installed at 3760 m a.s.l., 19834.7789N latitude, 103837.1809W longitude, within a forest where multi-century tree-ring ...

The main objective was to investigate malaria transmission dynamics in three different sites, two highland villages (Fort Ternan and Lunyerere) and a lowland peri-urban area (Nyalenda) of Kisumu city. Adult mosquitoes were collected using PSC and CDC light trap while malaria parasite incidence data was collected from a cohort of children on monthly basis. Rainfall, humidity and temperature data...
