Abstract
Abstract. Severe convective storms are responsible for large amount of damage each year around the world. They form an important part of the climate system by redistributing heat, moisture, and trace gases, as well as producing large quantities of precipitation. As these extreme and rare events are in mesoscale there is many uncertainty in predicting them and we can’t rely on just models. On the other hand, remote sensing has a large application in Meteorology and near real time weather forecasting, especially in rare and extreme events like convective storms that might be difficult to predict with atmospheric models. On second of June 2014, near 12UTC a sudden and strong convective storm occurred in Tehran province that was not predicted, and caused economic and human losses. In This research we used satellite observations along with synoptic station measurements to predict and monitor this storm. Results from MODIS data show an increase in the amount of cloudiness and also aerosol optical depth and sudden decrease in cloud top temperature few hours before the storm occurs. EUMETSAT images show the governing of convection before the storm occurs. With combining the observation data that shows Lake of humidity and high temperature in low levels with satellite data that reveals instability in high levels that together caused this convective, we could track the storm and decrease the large amount of damage.
Highlights
Convective storms play a vital role in weather and climate
In this study we used satellite images along with observation data to monitor the storm occurred on second of June 2014 in Tehran province. This storm was an extreme event in Tehran province and wasn’t predicted accurately and caused a huge damage
As we know models might have some uncertainty in predicting mesoscale phenomena like convective storms
Summary
Convective storms play a vital role in weather and climate. They act to redistribute heat, moisture, and trace gases in the vertical and horizontal. In the tropics and in the warm season in mid-latitudes, they provide a large amount of the precipitation. When convection is strong, the resulting weather can have bad effects on life and property and is typically referred to as severe. Definitions of what is called severe vary from place to place, in general, hail, high winds, tornadoes, and extremely heavy precipitation leading to flash flooding frequently are considered (Brooks & Dotzek, 2008). The term Mesoscale Convective System (MCS) is virtually uniquely associated with the satellite perspective (Doswell III, 2001)
