Transcript of Arabian Peninsula
The Arabian Peninsula is located of the border of Syria.
Much of the Arabian Peninsula is covered in desert.
The Arabian Desert lies in the middle of the Arabian Peninsula.
The main seas near the Arabian Peninsula are the Arabian Sea, the Red Sea, the Mediterranean Sea, the Black Sea, the Caspian Sea, and the Aral Sea.
The Anatolian Plateau, the An Nafud desert, the Ar Rub’ Al Khali Desert, the Arabian Desert, the Asir and Hijaz Mountains, and the Caucasus Mountains are all important landforms in the Arabian Peninsula.
The Arabian Sea has the North Equatorial current flowing through it.
In the desert, the sun absorbs the heat and radiates it back into the air
.The North Easterly trade winds occur here.
The Asir and Hijaz mountains experience a process called orographic lifting.
They also get a rain shadow
Climate of the Arabian Peninsula
The Arabian Peninsula has two seasons; summer and winter
Historical Weather in the Arabian Peninsula
In the Arabian peninsula the temperature is very hot
Summer heats reach up to 129 degrees Fahrenheit (54 degrees Celsius)
There is a lot of cites on the coast because there is a sea breeze which makes it cooler
3 day weather forecast
2014 left and 2010 right
This is a comparison of the two weather charts for temperatures. The red line being the highs and the blue line being the lows.
The wind speeds have changed. This is explained by the fact that uneven heating isn't always the same and the graph is for one city.
The humidity of Riyadh, Saudi Arabia is almost completely the same except for a few minor changes because weather doesn't always stay the same
Maps are for Riyadh, Saudi Arabia
The precipitation has changed. This is most likely due to a drought in the Arabian Peninsula which changed the readings of rain on the graph.
There are many droughts in the Arabian peninsula because of the lack of water
Summers in the Arabian Peninsula are extreme.
The temperatures are pretty high and can reach as high as 130 degrees Fahrenheit.
In the interior it is very dry and have low humidity.
The coastal areas /highlands experience high humidity & dew/ fog at night and early morning.
Rainfall average in the desert is only 4 in.
Heavy rains accompany monsoon winds from Indian Ocean. This often causes flooding.
Monsoons: In summer months, the Arabian Peninsula's weather can get really high while the Indian Ocean is much cooler. "The warm air over the land rises and cooler moist air blows in from the sea, bringing heavy rains to the region" (meeting organizer).
Also, during the summer, there is a current in the Arabian Sea called the Somali Current. When this current merges with the Southwestern Monsoon Current along the northeast coast of the Arabian Peninsula, there is a severe upwelling in the water and can cause flooding.
There is rain, atmospheric moisture, dust storms.
Torrential downpour causes floods in watersheds.
Winters are cool. The most frigid weather in high altitudes in north. In these northern areas there may be ice & snow
There are two times in the year where it is more windy than usual. One is from December to January and the other is from May to June. These winds often cause a lot of sandstorms.
Earth is severely affected by climate change
especially global warming ( melting ice, sea level rise, flooding, ecosystems out of balance, stronger storms )
rainfall increased in the first period (1979–1993),
decreased in the second period (1994–2009).
The decrease rate is 35.1 mm per decade in wet seasons.
The temperature over Saudi Arabia has increased by 0.72 °C per decade in dry seasons compared to the wet season (0.51 °C per decade).
In the years to come...
extreme dry heat started in the 20th century
more warm days & nights
large variations in daily weather
cause thought to be global warming

This is a sandstorm, which is a very severe weather condition here in the Arabian Peninsula
In desert regions at certain times of the year, sandstorms become more frequent because the strong heating of the air over the desert. This causes the lower atmosphere to become unstable. This instability mixes strong winds in the middle troposphere downward to the surface, producing stronger winds at the surface. This strong wind blows sand dunes which cause large amounts of sand to go with the wind.
The Arabian Peninsula has a history of powerful storms
Hurricanes sometimes hit the Arabian Peninsula
They are caused warm, moist air rising from the ocean
Hazards of hurricanes are debris from the wind damage, storm surges and heavy rain that can cause flooding people's homes, and may sometimes cause tornadoes, which can also do heavy damage.
Cyclone Gonu hit Oman on June 6, 2007, which was a category 4 by then.
strongest storm since record keeping began in 1945
damaged bridges, roads, electricity and telephone poles.
killed 49 people and caused 4 billion US dollars worth of damage
Cyclone Phet occurred on June of 2010
killed 24 people and injured another 10,000
it also destroyed 780 million worth of material loss
The country of Oman gets a lot of the hurricanes because it is closest to the ocean
Another hazard that happens on the Arabian Peninsula is sandstorms
Sandstorms are caused when storms pick up dust and sand from the desert surface and bring it into the cities.
Hazards of sandstorms are sand blowing, which can cause damage to buildings and harm people.
One of these such sandstorms happened on March 20, 2013
It was so powerful it was called a "super sandstorm"
made up of 2 different storms converging.
The first storm came from Iraq/Kuwait and the second one came from Southeastern Iran.
the dust plume stretched from the coast of Oman which is in the east, to India, which is in the west
many days of dust storm activity followed the plume
Another particularly powerful sandstorm happened on May 7, 2013.
It blasted over the cities of Riyadh and Bahram, and the country of Qatar
Weather Forecast with
How do Scientists predict weather?
Meteorologists monitor weather
They use a wide network of weather stations and satellite images to map out large air masses
using air masses meteorologists can predict fronts
barometer - air pressure
anemometer - wind speed
wind vane - direction of wind
psychometer - relative humidity
thermometer - temperature
rain gauge - amount of precipitation
Interesting Facts and Statistics
The Arabian Peninsula is the fourth hottest place on earth with the high temperature of 131 degrees Fahrenheit or 55 degrees celsius.
The part of the Arabian Peninsula that is known as Oman had the hottest low temperature of 107 degrees Fahrenheit or 42 degrees Celsius.
Saudi Arabia is the largest country in the world without a river.
Slavery was not abolished in Saudi Arabia until 1962.
How can communities prepare for natural disasters?
create an emergency kit which has canned food, batteries, flashlight, medications, important documents, and water
cloth yourself in a mask, goggles, and clothing that covers you face
have a safe room for your family
have a radio to be informed on the tornado
have an emergency kit
have an evacuation plan
build an emergency kit
cover all of your windows
find evacuation routes
reinforce garage doors
How can communications prepare for the natural disaster?
Communication is very important in the time of a natural disaster of severe storm. It can mean life or death. If a hurricane is coming for an area and if the area is warned ahead of time, then the people there can evacuate and get away safely. However, if the notice does not get there quick enough, then the area is just sitting there waiting for the storm to arrive.
Cause and Effects of Weather related disasters
The cause of natural disasters can be because of many different reasons. An underwater earthquake can cause a tsunami or a cold front and warm front meeting could cause tornado. The effect of them can ruin land, destroy the economy if it is specialized in anything, or can ruin peoples' home and livelihood.

Sand storms form when a a strong wind blows loose sand or dirt, also in deserts at certain times in the year sandstorms are much more frequent.
