Response of PM2.5 pollution to meteorological and anthropogenic emissions changes during COVID-19 lockdown in Hunan Province based on WRF-Chem model

Optimization and Evaluation of the Weather Research and Forecasting (WRF) Model for Wind Energy Resource Assessment and Mapping in Iran

“…Conversely, during the warm season, notable variations emerge, particularly in the eastern sectors of the country, where there is a markedly higher wind potential in A1 and A2. The maximum monthly averages of the wind speed in the A1 and A2 regions (12.5-14.5 m/s) in July-August (Figure 8) are similar to the measured wind speeds in Zabol, Sistan during the summer season [106,117]. The western border regions (A6 and A8), influenced by the northwesterly Shamal winds, also experience increased wind potential compared to the colder season.…”

“…However, the Kavir and Lut Deserts in the interior of Iran generally have low Aeolian potential on an annual basis, with a notable seasonality. The Aeolian regime in these desert regions, along with annual and intra-seasonal variability, play a significant role in land degradation and wind erosion from the deserts and arid rangelands in central Iran [115][116][117]. Certain valleys and wind corridors along the eastern borders of Iran exhibit wind speeds of up to class 6 in terms of the annual average wind speed categorization.…”

“…Characteristically, the annual mean simulated wind speed in the Manjil region is approximately 7.82 m/s, in Kahak it is 6.71 m/s, and in Binaloud it is 7.11 m/s, corresponding to wind classes 5, 3 and 4, respectively. It is observed that possible wind farms in the Sistan Basin in eastern Iran would fall into the upper class 7, as the annual mean wind speed has been measured at above 8-10 m/s at the Zabol station over the long term [106,117,118]. However, despite this very outstanding wind energy potential in the Sistan Basin and surrounding areas, no wind farms or Aeolian Parks have been developed there so far.…”

“…Sci. 2024,14, x FOR PEER REVIEW 20 of 29 ured wind speeds in Zabol, Sistan during the summer season[106,117]. The western border regions (A6 and A8), influenced by the northwesterly Shamal winds, also experience increased wind potential compared to the colder season.…”

Linkage between Airborne Particulate Matter and Viral Pandemic COVID-19 in Bucharest

“…Its climate is temperate continental, with western European climate circulation The function of age, the strength of the immune system, seasonal or local and regional atmospheric circulation and weather conditions, geographic location, and epidemiologic studies found that both short-term and long-term exposure to high levels at the ground or street-level PM and bioaerosols concentrations can be linked with a variety of airway diseases seasonality and increased respiratory system symptoms, including rhinitis, airway inflammation, asthma, bronchitis, organic dust toxic syndrome, seasonal influenza, severe acute respiratory syndrome, and coronavirus disease (COVID-19), through lung function decrease and the development of different respiratory symptoms (cough, shortness of breath, pain on deep inspiration, etc.) [52][53][54][55].…”
