There are two main factors.
The first is that the UAE borders the Arabian Gulf, this is a shallow sea to the north of the country, this is a closed system (entrance and exit at the Straits of Hormuz). In summer the water temperature heats up and there is a lot of local evaporation from the Gulf, resulting in elevated humidity levels along the coastal areas. The water temperature can reach 35 degree Centigrade over summer!
The second major influence is the influx of warm humid air form the Indian Monsoon system which is prominent over the Indian ocean to the south east of the Arabian peninsula during the summer months. While the area does not benefit from the rain that this system brings to the Indian subcontinent, it does increase the humidity.
During summer a good hot day will be about 45 degrees Celsius, although it can top just on 50 degrees on the odd day (at midday)
Humidity is typically highest during the summer months, when warm air holds more moisture. This is due to increased evaporation from bodies of water and higher temperatures leading to more water vapor in the air.
Yes, but not on a very wide scale. The humidity and high temperatures do not allow for the production during summer and the costs of cooling large greenhouses is outweighed by a cheaper import price for the product. In winter they can be grown, but normally only inland areas (commercial production).
Humidity is generally higher in summer than in winter.
The highest relative humidity in Sacramento typically occurs during the late fall and winter months, particularly from November to March. During this time, cooler temperatures and increased rainfall contribute to higher humidity levels. Conversely, the summer months tend to have lower humidity due to the hot, dry climate.
The most common seasonal plants in the UAE are: Portulaca and Vinca (Catharanthus) in summer and Petunias in winter
The UAE is a desert, it is not tropical. Although in summer it can be extremely humid (almost the smae as tropical countries), but has no rain during this period.
Arizona typically has the lowest humidity levels in the United States due to its predominantly arid climate. Areas such as Phoenix and Tucson have very low humidity levels, especially during the summer months.
The humidity outside is very high.ORDuring the summer the humidity in the air is usually higher than in winter.
Potential evapotranspiration is typically highest in hot, dry conditions with high solar radiation and low humidity. This is because the rate of evaporation from the soil and transpiration from plants increases under these conditions.
Clothes dry faster in summer because dry air in summer and no humidity.
