Abstract EN
Monitoring and prediction of the climatic phenomenon are of keen interest in recent years because it has great influence in the lives of people and their environments.
This paper is aimed at reporting the variation of daily and monthly solar radiation, air temperature, relative humidity (RH), and dew point over the year of 2013 based on the data obtained from the weather station situated in Damak, Nepal.
The result shows that on a clear day, the variation of solar radiation and RH follows the Gaussian function in which the first one has an upward trend and the second one has a downward trend.
However, the change in air temperature satisfies the sine function.
The dew point temperature shows somewhat complex behavior.
Monthly variation of solar radiation, air temperature, and dew point shows a similar pattern, lower at winter and higher in summer.
Maximum solar radiation (331 Wm-2) was observed in May and minimum (170 Wm-2) in December.
Air temperature and dew point had the highest value from June to September nearly at 29°C and 25°C, respectively.
The lowest value of the relative humidity (55.4%) in April indicates the driest month of the year.
Dew point was also calculated from the actual readings of air temperature and relative humidity using the online calculator, and the calculated value showed the exact linear relationship with the observed value.
The diurnal and nocturnal temperature of each month showed that temperature difference was relatively lower (less than 10°C) at summer rather than in winter.
