Ch4. Clouds

Question 1

Which of the following clouds may extend into more than one level?

Nimbostratus

Answer 1

Orografik olarak yükselebilir.

Question 2

Which of the following cloud types will most probably form when cold moist air moves over a warm surface ?

Cumulus

Answer 2

Cumulus dikey - Stratuslar varsa yatay.

Question 3

In mid latitudes, the tops of Cumulus are often limited by

A temperature ______

Answer 3

İnversion.

Cumulus bulutlarının dikey gelişimini genelde bir sıcaklık enverziyonu durdurur.

Question 4

In wintertime stratus is often formed when warm maritime air moves over cold land. How can such clouds be classified ?

Turbulence clouds.

Answer 4

Stratus türbülanstan dolayı oluştuğu için “türbülans bulutu” olarak sınıflandırılır ancak içindeki türbülans hafiftir.

Türbülanstan dolayı aşağı yukarı hareket eden hava 100% bağıl neme ulaştığında ince bir tabaka halinde stratus bulutları oluşturabilir.

Question 5

What process in an air mass leads to the creation of wide spread NS and AS cloud coverage?

Lifting

Answer 5

Warm front - cephesel kaldırma (frontal lifting) sayesinde NS AS CS gibi stratiform bulutlar oluşur.

Question 6

The main components of an altostratus are

____ crystals and water droplets

Answer 6

Ice…

*water vapour bir bulut bileşeni değildir. Bulut oluşumu için su damlacıklarına dönüşmesi gerekir.

Ice pellets ve snow grains yağış tipleridir. Bulut bileşeni değildir.

Question 7

Grey cloud layer often dark, blot out the sun…

Nimblot

Answer 7

Nimbostratus

Question 8

Fair weather cumulus clouds often indicate.

Turbulance ___ and ___ cloud level

Answer 8

At and below cloud…

Bulutların altında da convektif akım var.

Question 9

In towering cumulus clouds

STRONG updraughts occur and the temperature in the cloud is ____

Answer 9

Higher (condensation’dan dolayı latent heat dissipates)

Question 10

Cold moist air moves over a warm surface… Cumulus

Answer 10

Soğuk nemli hava, sıcak zemin üzerinden geçerken alttan ısınır ve yükselir. Dikey gelişimli.

Question 11

Which of the following processes contributes to the formation of frontal fog?

____ falls from the warm air into the cold air

Answer 11

Rain.

Frontal fog sıcak cephenin önünde oluşur. Sıcak havadan soğuk havaya düşen yağmur damlaları nem kattığı için sis oluşumu gözlenebilir.

Question 12

Advection fog can be formed when

______ moist air flows over a colder surface

Answer 12

Warm.

Advection fogda warm air sisi oluştururken, steam fogda cold air moving over warm water sis oluşturur.

Question 13

What kind of fog is often observed in the coastal region of Newfoundlandv in spring time?

Adv
Rad
Steam
Frontal

Answer 13

Advection fog notları:

• warm moist air flows over a colder surface
• newfoundand labrador cold sea current
• an air mass moving inland from the coast in winter.

Question 14

If radiation fog forms on a clear night with light winds, the increase in wind speed from 5 kt to 13 kt will most likely

Cause the fog to lift and become low _______

Answer 14

Stratus.

Question 15

Radiation fog most frequently occurs in:

_____ pressure systems over land.

Answer 15

High.

Radiation fog notları:

- moist air over land
- high pressure
-winds below 5 kt
- shortly after sunrise (coldest time)
-average height 500 ft

• dissipated by surface heating or increase in wind speed.

Question 16

Radiation fog most frequently occurs in:

_____ pressure systems over land.

Answer 16

High.

Radiation fog notları:
- after a clear night
- moist air over land
- high pressure
-winds below 5 kt
- shortly after sunrise (coldest time)
-average height 500 ft

• dissipated by surface heating or increase in wind speed.

Question 17

Which of the following sets of conditions are most likely to lead to the formation of advection fog?

A mild moist airstream flowing over ______ surfaces with the wind speed _____ than 15 kt.

Answer 17

Colder surfaces
Wind speed Less than 15 kt.

Question 18

As a result of diurnal variation radiation fog is lifted and a cloud cover is formed. Which statement is true?

Low stratus will develop caused by _______ wind speed.

Answer 18

Increasing.

Rüzgar hızlanınca sisi yukarı taşıyor.

Question 19

If a radiation fog forms on a clear night with light winds, the increase in wind speed from 5 kt to 13 kt will most likely

Cause the fog to ____ and become _____ _______

Answer 19

Lift and become low stratus.

Question 20

Snow grains fall from stratus or supercooled ___

Answer 20

Fog.

Question 21

With what type of cloud is “GR” precipitation most commonly associated?

Answer 21

Cumulonimbus. YunanRte
Grail = Hail

Question 22

Large hail stones are typically associated with s____ th______

Answer 22

Severe thunderstorms

Question 23

Hazardous hailstones, REACHING THE GROUND, are most likely to be experienced below CB clouds situated

In ________ interiors in ______ latitudes

Answer 23

Continental, middle

Karada daha sert kış olur. Ekvatorda dolular yere kadar düşemez.

Question 24

With what type of cloud is heavy precipitation UNLIKELY during the summer months?

SC, AS

Answer 24

İçinde nimbo geçen bulutlar yağış üretmeye meyillidir. Dolayısıyla NS ve CB geçen seçenekleri direkt eleyelim.

• soruları dikkatli oku. (Unlikely)

Question 25

Freezing precipitation occurs mainly in the form of freezing ____ or freezing _____

Answer 25

Freezing rain or freezing drizzle.

Only geçen sorulara şüpheyle bak.

Question 26

Solid precipitation which is transparent or translucent and has a diameter of 5mm or less formed by the freezing of raindrops or refreezing of melted snow, and usually bounces off hard surfaces, is a description of

Answer 26

Ice pellets bounces off hard surfaces.

Question 27

The presence of ice pellets at the surface is the evidence that:

Temperatures are ______ freezing at some higher altitudes.

Answer 27

Ice pellets, yağmurun donması ya da eriyen kar tanesinin tekrar donması durumunda oluşur. Bundan dolayı daha yukarda sıcaklık yüksek.

Freezing rain düşerken daha da soğursa ice pellets oluşur.
