Climate, Weather, and Geography

The term 'hurricane' is used specifically for tropical cyclones in the Atlantic and Northeast Pacific. The same weather phenomenon is called 'typhoon' in the Northwest Pacific. Other regional names include 'cyclone' in the Indian Ocean and 'tropical cyclone' in the Southwest Pacific. The other options are geological features unrelated to weather.

Moraines are accumulations of unconsolidated debris (rock, soil, gravel) deposited by glaciers. They form at the sides (lateral moraines), between glaciers (medial moraines), or at the terminus (terminal moraines). Ablation is ice loss, sleet is precipitation, cliffs are erosional features, and pampero is a wind type.

The Pampero is a cold, dry wind that blows from the Andes mountains across the Pampas grasslands of Argentina. It typically occurs in winter and can bring sudden temperature drops and gusty conditions. Ablation relates to ice, sleet is precipitation, cliffs are landforms, and moraines are glacial deposits.

Sleet is frozen precipitation consisting of small ice pellets formed when raindrops fall through a cold layer of air and freeze before reaching the ground. It's different from snow (which forms directly as ice crystals) and freezing rain (which freezes on contact with surfaces). Ablation is ice loss, cliffs are landforms, pampero is a wind, and moraines are glacial deposits.

 Low lying clouds reflect back infrared radiations.

As there is no comparison therefore, 'higher' should be replaced by 'high'. 

Cumulonimbus clouds are the characteristic cloud type of thunderstorms, distinguished by their tall vertical development reaching through multiple atmospheric layers. These clouds form in unstable conditions and produce heavy rain, lightning, and sometimes hail.

Altostratus clouds are mid-level clouds that typically indicate stable atmospheric conditions. Unlike convective clouds like cumulonimbus or altocumulus, altostratus clouds form in stable air and generally provide smooth flying conditions with minimal turbulence.

Hoar frost forms when air temperature is below the frost point, causing water vapor to deposit directly as ice crystals on surfaces without passing through a liquid phase. This differs from rime and glaze ice which involve supercooled liquid water freezing on contact.

Thunderstorms require a steep lapse rate (rapid temperature decrease with altitude) to create strong upward air currents. This atmospheric instability allows warm air to rise rapidly, forming the tall cumulonimbus clouds essential for thunderstorm development.

Thunderstorm formation requires vertical lifting mechanisms: solar heating (thermal), orographic lifting (terrain), and frontal lifting (weather fronts). Dust storms involve horizontal particle movement but do not provide the upward air motion needed for convective storm development.

The mature stage of a thunderstorm is characterized by the simultaneous presence of both updrafts and downdrafts. Updrafts continue to fuel the storm's growth while downdrafts begin to develop as precipitation falls, creating the characteristic intense precipitation and turbulence of this stage. The formation stage has only updrafts, while the dissipating stage has primarily downdrafts.

The dissipating stage of a thunderstorm is characterized by the dominance of downdrafts throughout the cloud structure. By this stage, the updrafts that initially fueled the storm's growth have weakened and disappeared, leaving only downdrafts that continue to bring precipitation downward. The mature stage has both updrafts and downdrafts, while the formation stage has only updrafts.

Advection fog forms when relatively warm and moist air moves horizontally (advects) over a colder surface such as cold ground, water, or snow. The cold surface cools the air from below to its dew point, causing condensation and fog formation. This differs from radiation fog (formed by ground cooling at night) and steam fog (formed when cold air moves over warm water).
