Research Paper: The Effect of Wind Stress on Thermocline Development in Persian Gulf in Summer [PDF]

فیزیک کاربردی ایران, 2021
Persian Gulf (PG) is a shallow semi-enclosed sea that connects to the open ocean through the Strait of Hormuz. Thermocline occurs as a sharp decrease in temperature with depth in the subsurface layer as a result of water column classification in Persian ...

Improving the Gaussianity of radar reflectivity departures between observations and simulations using symmetric rain rates [PDF]

Atmospheric Measurement Techniques
Given that the Gaussianity of the observation error distribution is the fundamental principle of some data assimilation and machine learning algorithms, the error structure of radar reflectivity has become increasingly important with the development of ...
