Meteorological conditions affecting electromagnetic propagation on the Arabian Peninsula
Wayne F. Petersen
Electromagnetic waves are effected by the medium they are propagating in. Even in the vacuum of space, they are affected by gravity (look up gravity lens). There are two paramaters that are most fundamental. The permittivity of a medium describes. The electromagnetic disturbance that results is propagated with the electronic (E) and magnetic (B) vectors vibrating perpendicularly to each other and also to the direction of propagation (Z). The frequency, n, is determined by the oscillator, while the wavelength is determined by the oscillation frequency divided by the velocity of the wave.
The exact choice of M 0 (usually taken in the interval [–] M‐units/m) does not affect the propagation pattern since it is the derivative of M that dictates wave propagation in the medium [Hitney, ; Gerstoft et al., ].The assumption of neutral stability implies that the air and sea‐surface temperature difference is nearly. The propagation speed varies accordingly depending upon the various characteristics of the medium and instance, the electromagnetic wave, the mechanism of propagation involves mutual generation of periodically varying electric and magnetic fields .
Electrodynamics is the physics of electromagnetic radiation, and electromagnetism is the physical phenomenon associated with the theory of electrodynamics. Electric and magnetic fields obey the properties of , a field due to any particular particle or time-varying electric or magnetic field contributes to the fields present in the same space due to other causes.

One of the most important atmospheric affects is ducting of electromagnetic energy by refractive layers in the atmosphere.
To assess the affects of ducting on electromagnetic emissions around Dhahran, Saudi Arabia, a geometric optics model of wave propagation developed by Raymond P. Wasky was modified and : Wayne F. Petersen. Meteorological conditions affecting electromagnetic propagation on the Arabian Peninsula.
By Wayne F. Petersen Download PDF (7 MB)Author: Wayne F. Petersen. Natural and anthropogenic aerosols over the Arabian Peninsula (AP) (Fig. 1a) play a major role in regional and global climate change, influencing the radiation budget, and affecting the regional hydrological lack of environmental studies on the AP is a direct result of its harsh environmental conditions, however, the latest generation of space-borne sensors, along with.
The climate of the Arabian Peninsula is characterized by significant spatial and temporal variations, due to its complex topography and the large-scale atmospheric circulation. Furthermore, the role of dust in the formation of regional climate is considered to be crucial.
In this work, the regional climatology for the Arabian Peninsula has been studied by employing a high resolution state of. For this purpose, two simulations are performed, one with a high horizontal resolution (at ° × °) and one with a lower horizontal resolution (at ° × °), both of which covered two intense dust storms that occurred on 17–20 March that spanned over thousands of kilometres affecting the whole Arabian Peninsula.
More details about the radiosonde and the special climate of Arabian Gulf gradient affect electromagnetic wave propagation in the atmosphere. with local meteorological conditions and. The propagation of electromagnetic (EM) waves of frequencies above MHz is affected by the existence and properties of the atmospheric duct, i.e.
a horizontal layer in the lower atmosphere in which radio signals propagate more efficiently. Atmospheric ducts can be found in many parts of the world ocean including the Arabian Gulf.
The methodology adopted for this study is an integrated approach of synoptic analysis. This approach requires an investigation of several weather parameters and satellite imagery to identify the meteorological conditions that led to the strong winds capable of generating the March dust event as well as the associated supportive environmental conditions.
The propagation of electromagnetic waves emitted from ground-based meteorological radars is determined by the stratification of the atmosphere. In extreme superrefractive situations characterized by strong temperature inversions or strong vertical gradients of moisture, the radar beam can be deflected toward the ground (ducting or trapping).
WEATHER VERSUS PROPAGATION. Weather is an additional factor that affects the propagation of radio waves. In this section, we will explain how and to what extent the various weather phenomena affect wave propagation. Wind, air temperature, and water content of.
Atmospheric variables that affect EM propagation include temperature, moisture, pressure, and composition (gases, aerosols, and particulates). These variables control processes including refraction, absorption, and scattering. The full range of the electromagnetic spectrum covers.
Radio propagation is the behavior of radio waves as they travel, or are propagated, from one point to another, or into various parts of the atmosphere. As a form of electromagnetic radiation, like light waves, radio waves are affected by the phenomena of reflection, refraction, diffraction, absorption, polarization, and scattering.
Understanding the effects of varying conditions on radio. where denotes the forward scattering amplitude of a raindrop with radius a, and n(a)da is the number of drops per cubic meter in space with radius a in range da and is a function of rainfall rate R. (Note that the discussion in Sections 2–6 is based on the single-scattering approximation.) Since the propagation factor in a rain medium is exp(−ikr), the real and imaginary parts of k are.
The wind systems in the Arabian Sea are controlled by various factors that include the dynamics involved and the region of formation and propagation. The low‐level jets (LLJ) are the most influencing wind systems that affect the ocean surface.
The Findlater jet is the basis for southwest (SW) monsoon winds (Findlater, ). It is the prime. The main objective of the Passive seismic IPDS survey campaigns in the Arabian Peninsula in Oil and Gas fields (UAE, Kuwait, & Jordan) was to run such surveys as an exploration, delineation.
OBJECTIVE -he objective oi this thesis is to determine the synoptic meteorological conditions that uill severely affect electro- magnetic (EM) propagation on the Arabian Peninsula. Atmos- pheric refractivity, surface and elevated ducts, and lanJ- sea breeze will be addressed.
Electromagnetic waves are not deflected by electric or magnetic field. These waves can be polarized. Electromagnetic Waves undergo interference and diffraction. The wavelength(λ) and frequency (v) of the EM waves can be related as: c= v.λ.
where c = velocity of the wave. To study the electromagnetic wave propagation let us study the example. This device could be applicable for continuous monitoring of antenna block CRC of radio engineering system at electromagnetic waves propagation in the MHz frequency band. Modernized microwave units CRC measurement offering in this project will substantially increase stability and accuracy of the CRC module and argument measurements.
PROPAGATION OF ELECTROMAGNETIC WAVES _ PART 02 - Duration: 7activestudioviews. Electromagnetic waves and the electromagnetic spectrum | .1. Introduction  The global hydrological cycle is supplied annually with circa km 3 of water evaporated from the Earth's surface, with the bulk of this volume evaporating from the oceanic surface (86%) and only 14% from continents [Oki, ].The vast majority of the water evaporated from the oceans (90%) precipitates back onto oceans while the remaining 10% is transported to.
