Cloud Cover Types in August


5/10

The fraction of time spent in each of the five sky cover categories. From top (most blue) to

bottom (most gray), the categories are clear, mostly clear, partly cloudy, mostly cloudy,

and overcast. Pink indicates missing data. Outside of the United States clear skies are often

reported ambiguously, leading them to be lumped in with the missing data.

Precipitation

The probability that precipitation will be observed at this location varies throughout the

month. Precipitation is most likely around August 31, occurring in 6%of days.

Precipitation is least likely around August 1, occurring in 2%of days.

Probability of Precipitation at Some Point in the Day in August

The fraction of days in which various types of precipitation are observed. If more than one

type of precipitation is reported in a given day, the more severe precipitation is counted. For

example, if light rain is observed in the same day as a thunderstorm, that day counts

towards the thunderstorm totals. The order of severity is from the top down in this graph,

with the most severe at the bottom.

Throughout August, the most common forms of precipitation are thunderstorms,

moderate rain, light rain, and drizzle.

Thunderstormsare the most severe precipitation observed during 40%of those days

with precipitation. They are most likely around August 30, when it is observedduring 2%of all days.

Moderate rainis the most severe precipitation observed during 32%of those days with

precipitation. It is most likely around August 31, when it is observed during 3%of all

days.

Light rainis the most severe precipitation observed during 16%of those days with


days.


6/10

Drizzleis the most severe precipitation observed during 10%of those days with


days.

Types of Precipitation Throughout August

Relative frequency of various types of precipitation over the course of a typical August.

Snow

Either snow is exceptionally unlikely to fall at this location in August or this station does

not reliably report precipitation types.

Humidity

The relative humidity typically ranges from 32%(comfortable) to 94%(very humid)

over the course of a typical August, rarely dropping below 17%(dry) and reaching as

high as 100%(very humid).

The air is driestaround August 18, at which time the relative humidity dropsbelow 41%(comfortable) three days out of four; it is most humidaround August 30,

rising above 93%(very humid) three days out of four.


7/10

Relative Humidity in August

The average daily high (blue) and low (brown) relative humidity with percentile bands (inner

bands from 25th to 75th percentile, outer bands from 10th to 90th percentile).

Dew Point

Dew point is often a better measure of how comfortable a person will find the weather

than relative humidity because it more directly relates to whether perspiration will

evaporate from the skin, thereby cooling the body. Lower dew points feel drier and

higher dew points feel more humid.Over the course of a typical August, the dew point typically varies

from 14C(comfortable) to 22C(very muggy) and is rarely below 9C(dry) or

above 25C(oppressive).


8/10

Dew Point in August

The daily average low (blue) and high (red) dew point with percentile bands (inner band

from 25th to 75th percentile, outer band from 10th to 90th percentile).

Wind

Over the course of August typical wind speeds vary from 0 m/sto 8 m/s(calm to

moderate breeze), rarely exceeding 10 m/s(fresh breeze).

The highestaverage wind speed of 4 m/s(gentle breeze) occurs around August 25, atwhich time the average daily maximum wind speed is 8 m/s(moderate breeze).

The lowestaverage wind speed of 4 m/s(gentle breeze) occurs around August 2, at

which time the average daily maximum wind speed is 7 m/s(moderate breeze).


9/10

Wind Speed in August

The average daily minimum (red), maximum (green), and average (black) wind speed with

percentile bands (inner band from 25th to 75th percentile, outer band from 10th to 90th

percentile).

The wind is most often out of the east (12%of the time).

Wind Directions in August

The fraction of time spent with the wind blowing from the various directions over the entireyear. Values do not sum to 100% because the wind direction is undefined when the wind

speed is zero.


10/10

Fraction of Time Spent with Various Wind Directions in August

The fraction of time spent with the wind blowing from the various directions on a daily basis.

Stacked values do not always sum to 100% because the wind direction is undefined when

the wind speed is zero.

Climate

Tripoli has a hotsubtropicalsemi-arid climate(Kppen climate classificationBSh)[17]

with long, hot

and dry summers with relatively wet and mild winters with aMediterranean(dry-summer) rainfall

pattern. Its summers are hot with temperatures that often exceed 38C(100F); average July

temperatures are between 22 and 33 C (72 and 91 F). In December, temperatures have reached

as low as 0 C (32 F), but the average remains at between 9 and 18 C (48 and 64 F). The

average annual rainfall is less than 400 millimetres (16 inches), and can be very erratic. But snowfall

has occurred in past years.[18]

For example, epic floods in 1945 left Tripoli under water for several days, but two years later an

unprecedenteddroughtcaused the loss of thousands of head of cattle. Deficiency in rainfall is no

doubt reflected in an absence of permanent rivers or streams in the city as is indeed true throughout

the entire country. The allocation of limited water is considered of sufficient importance to warrant

the existence of theSecretariat of Dams and Water Resources,and damaging a source of water can

be penalized by a heavy fine or imprisonment.

TheGreat Manmade River,a network of pipelines that transport water from the desert to the coastal

cities, supplies Tripoli with its water.[19]

The grand scheme was initiated by Gaddafi in 1982 and hashad a positive impact on the city's inhabitants.Tripoli is dotted with public spaces, but none fit under

the category of largecity parks.Martyrs' Square,located near the waterfront is scattered withpalm

trees,the most abundant plant used for landscaping in the city. The Tripoli Zoo,located south of the

city centre, is a large reserve of plants, trees and open green spaces and is the country's biggest

zoo]It has, however, been closed since 2009.
