Mehrabad Weather Station

Mehrabad airport synoptic weather station officially started its activity with the beginning of World War II in order to provide weather reports. This station is an airport and upper atmosphere synoptic station, whose synoptic activity includes measuring, recording and reporting various atmospheric parameters such as wind direction and speed, cloudiness, detecting various atmospheric phenomena, etc. in the form of synoptic, meter and spatial reports. and it is provided to the watch tower and at the same time it is sent to the forecast center of the country's meteorological organization for review to issue a forecast.

In the upper atmosphere section, a radiosonde with a balloon is released in the sky in two shifts at 00:00 and 12:00 hours (UTC) to check the atmospheric conditions in the upper atmosphere. The information obtained from Radio Sound is drawn by the plotter on the Scioti map. Using this map, parameters such as water vapor pressure, saturated vapor pressure, potential temperature, mixing ratio, relative humidity, wet temperature, equivalent temperature, equivalent potential temperature, virtual temperature, pressure model (L-C-L) and also Obtained indices (SI, KA-I) which are criteria for detecting instability and cumulonimbus cloud formation and occurrence of lightning.

Climatic characteristics in the general scale of the region, like other parts of Tehran province, are affected by the northern, northwestern and western systems, especially the southwestern, and its atmospheric precipitation, which starts from the months of November and December and continues until the middle of May, in the cold seasons of the year.

The sum of thermal units above zero degree days and the sum of thermal units above ten degrees days have been obtained.
The average number of freezing days with thresholds of zero, -4 is 50, 12 days respectively.
The annual average relative humidity is 41% and the maximum and minimum averages are 56% and 28%, respectively.
The total annual evaporation from class A pan is more than 2500 mm. January and July have the lowest and the highest amount of evaporation, respectively.
