How Haboob affects aviation and pilot's visibility

Abstract

The following paper focuses on storms, specifically Haboob (hebbe), how its is formed the process cycle where generally haboob occurs. How and why haboob affects the Aircrafts and pilots visibility. For this, I've researched on storm especially wind and sand storms, how they are formed and aircrafts aviation, and how these windstorms particularly Haboob, affects on aircrafts and pilots visibility.

How Haboob affects aviation and pilot's visibility

Introduction

Sandstorm or dust storm accompanied by strong winds carrying small particles of sand or dirt into the air, forming a lens shaped gain-antic dust wall, particularly in drought areas, Followed by a heavy rain fall. The word Haboob, is a name for such a weather condition. In a Haboob the thunderstorm lift up the sand or dust into a huge, tumbling dark cloud like a wall that may extend horizontally for over a hundred kilometers and rise vertically to the base of the thunderstorm. Sudden increases in wind strength with a change in its direction with very low visibility are all the common signs that a Haboob is coming. In the following report highlights what is Haboob, how and why it is formed, and the factors effecting an aircraft and pilot visibility during a Haboob.



Discussion

Aviation

Aviation is derived from the latin word for bird, avis. Aviation is the arts and science for flying any aircraft, basically aviation includes the design, production and use and operation of aircrafts. There are two basic types of aviation's, civil and military aviation. For commercial and forces.

Haboob

The name haboob is derived from an Arabic word "habb", meaning wind, It is also known as Hebbe which is also an Arabic word meaning “blown” or “to blow”. They mostly occur in sandy or dusty places. Once they are formed in a deserts or any empty field, they gather strength and tons of dirt, grit, and sand as they move forward, and within no time there are clouds of dust stretched miles across and rise thousands of feet above the sea level.

What is it?

Haboob is a combination of strong wind with violent sandstorm forming a huge dust wall. The haboob usually forms as a cold downdraft inside an intense thunderstorm that sinks to the ground and spreads laterally outwards. The leading edge of the cold air is called the gust front, lifts dust or sand into huge tumbling dark cloud that can turn the sky dark. This darkening of the sky is why dust storms during the 1930s were sometimes referred to as black blizzards. The leading edge of haboob is called the dust wall may extend vertically to a height of more than 3000ft with spinning whirls of dust forming along it. Surface wind speeds with a haboob are usually on the order of 30mi/hr, although winds exceeding 60mi/hr have been recorded

How is it formed?

Haboob are generally short-lived, they last for only few hours. Three basic stages are involved in haboob development: the updraft cumulus or the intial stage, the mature stage and the diminishing or dissipating ...
