forecasting of temperature is a very important in meteorology. air temperature prediction is of a concern in environment, industry and agriculture. temperature with precipitation are important factors in meteorology and are used in classification of climate. in this paper we want to predict average monthly temperature for chosen station of isfahan province. an artificial neural network is a pow...

Optical flow is one of the standard computer vision methods for computing motion vectors. The key idea is to derive motion vectors from intensity gradients and differences of subsequent images. This model is analogous to advection equations in meteorology which motivates testing the method for weather radar data. Also the computational simplicity of optical flow makes it an interesting alternat...

The radiative forcing of dust and its impact on precipitation over the West Africa monsoon (WAM) region is simulated using a coupled meteorology and aerosol/chemistry model (WRF-Chem). During the monsoon season, dust is a dominant contributor to aerosol optical depth (AOD) over West Africa. In the control simulation, on 24-h domain average, dust has a cooling effect (−6.11 W m−2) at the surface...

Lakes are hot spots of carbon cycles in inland aquatic systems. As a vital factor, meteorology, including air temperature, precipitation, wind speed and evapotranspiration, is profoundly affecting or even regulating the wetland-air CO2 exchanges. Compared with some other similar lakes China, largest shallow grass-type Baiyangdian Lake (BYDL) acts as sink on North China Plain. The purpose this s...

Numerical experiments were carried out using the Tel-Aviv University 2-D cloud model to investigate the effects of increased concentrations of Cloud Condensation Nuclei (CCN), giant CCN (GCCN) and Ice Nuclei (IN) on the development of precipitation and cloud structure in mixedphase sub-tropical convective clouds. In order to differentiate between the contribution of the aerosols and the meteoro...

15 20 25 2 ABSTRACT This paper presents the estimated response of three pollutants, ozone (O 3), particulate matter ≤ 10 µm (PM 10), and nitrogen dioxide (NO 2), to individual local meteorological variables in Melbourne, Australia, over the period of 1999 to 2006. The meteorological-pollutant relationships have been assessed after controlling for long-term trends, seasonality, weekly 30 emissio...

Through precipitation, the fields of meteorology and geomorphology are fundamentally linked, thus interdisciplinary efforts needed to advance understanding warning rainfall-driven geohazards. With a focus on recent specific post-fire debris flows in California, our presentation provides an overview benefits challenges working team meteorologists geomorphologists, as well results project demonst...
