We present estimates of turbulent fluxes of heat and momentum derived from low level (∼30 m) aircraft measurements over the tropical Eastern Pacific and provide empirical relationships that are valid under high wind speed conditions (up to 25 ms−1). The estimates of total momentum flux and turbulent kinetic energy can be represented very accurately (r2=0.99, when data are binned every 1 ms−1) b...

Based on the necessity for enclosure protection of temperature and relative humidity sensors installed in a hostile environment, a wind tunnel was used to quantify the time that the sensors take to reach equilibrium in the environmental conditions to which they are exposed. Two treatments were used: (1) sensors with polyvinyl chloride (PVC) enclosure protection, and (2) sensors with no enclosur...

Using ERA5 reanalysis data of ECMWF and the ultra-high voltage (UHV) transmission line icing observation system to analyze meteorological conditions conductor in Guizhou from January 24 29, 2018, Results show: The weather for this event are that temperature drops below 0°C, there is weak rainfall, humidity generally between 95% 100%; direction mainly northerly wind, with wind speed 2~6m/s; air ...

This study analyzes the irrigation water requirement of wheat in Beijing-Tianjin-Hebei region under changes meteorological factors conditions, using growth period data, and data from 197 stations, 1960 to 2019. The results show that: (1) annual average precipitation, wind speed, relative humidity a downward variation trend, while temperature shows an upward trend. Moreover, radiation exhibit ne...

The atmospheric boundary layer (ABL), an atmospheric region near the Earth's surface, is affected by surface forcing and is important for studying air quality, climate, and weather forecasts. In this study, long-term urban nocturnal boundary layers (NBLs) were estimated by an elastic backscatter light detection and ranging (LiDAR) with various methods in Wuhan (30.5° N, 114.4° E), a city in Cen...

The direction and speed of winds play an important role in the occurrence of pollutions and dust stormas well as location placement for the establishment of industries and the expansion of cities. Yazd is a dry area of Iran, and constantly exposed to the dust particles in the air; and this in terms of human life and health issues are of special importance. In this paper a day when due to the am...
