Monsoon in Pakistan

Also there is an updraft of the lighter moist warm air from the ground, which keeps the thunderstorms from dissipating. While the warm air is rising there is cold dry air that is causing a downdraft causing the heavy water droplets to fall. The most violent storms are known as supercell storms, which are also the most likely to produce tornadoes. The last factor needed to produce the tornado is the jet stream to be moving at least 150 mph.

The first thing that starts a tornado would be the winds. The wind updraft can form a funnel. This funnel is called a Mesocyclone and when the mesocyclone touches the ground it is considered a tornado. Clouds play an important role in forming tornadoes too. Some other clouds are called, Wall Clouds. These clouds protrude from the sky and look like a giant waves coming down about to crash on earth. When wall clouds form the sky might turn to a greenish color or some other color. This wall-cloud

During June and July aerosol loading was comparatively higher at around 2-6 km height compared to the rest of the months. This possibly explains the high values of COF (figure 15 (b)) at higher altitudes in these two months due to convection processes that might have contributed to the formation of CCN (Jiang et al., 2007; Jiang et al., 2011). Excess rainfall events during 2013 ISMR, had resulted in heavy wash out of aerosols in the entire season which can be observed from low AOF values. The month of June witnessed an early onset of monsoon because of which there were more washouts of aerosols and September being the offset phase of the monsoon, witnessed high aerosol loading. July and August witnessed low AOF values, except that August had higher value of nearly 30% than that of June which had nearly 10-25% at 0.5-2 km altitude range The aerosol loading during June, July and August above the lower troposphere up to 4-6 km altitude might have contributed to cloud formation at higher altitudes which can be seen in the COF values of nearly 10-20%, 15-20% and 10-30% respectively at 12-17 km height range.

Does North America receive most of its winds from the Northeast Trades, the Southeast Trades, or from the Westerlies?

Monsoons are one uncontrollable geographic factor that plays a huge role on the outcome of the world’s living conditions and adaptations. A monsoon is a seasonal prevailing wind that blows for a whole

They are known as convective storms. Cell thunderstorms form in regions where limited vertical wind shear is present. The winds direction or speeds do not abruptly change rapidly. Ordinary storms develop and mature through a cycle, as cell thunderstorms don’t have this development. Different conditions vary from warm air rising, random turbulent eddies and terrain. These are a few that can be a trigger to these more impactful storms.

The tendency towards more intense precipitation events is projected to the future. The more precipitation, the more risk of flooding.More heavy downpours may increase the likelihood of property damage, travel delays and disruption in

3. Windward side: humid air moves up the mountain’s slopes and cools to form clouds that produce precipitation; leeward side: the air is warm and very dry.

Each part of the world is different. From China to Australia or from the North

So the warm moist air creates clouds of rain and thunderstorm. Adding to that winds with different speed going in different directions assisting in expanding these great clouds of rain and thunderstorm. With

Precipitation Depending on the temperature, season, type of cloud, and other conditions, precipitation occurs when the water that has evaporated becomes so heavy the clouds cannot hold it anymore and it falls back to earth as rain, hail, sleet, or snow (The Water Cycle, 2009; Wilkinson, 2007).

Cumulonimbus clouds are mostly affiliated with thunderstorms, lightning, heavy rainfall, blizzard or hail. The forecast should reflect rain or chances of rain.

The ability help to develop the thunderstorms. The tornadoes happen more frequent in the noon and evening, right next to the heat of the day that has made the hot air that starts thunderstorm and remember a thunderstorm leads to a tornado. Thunderstorm can happen when moist and warm air gets stuck by warm, dry air below a layer of cool dry air this is call an inversion.Most tornadoes come from thunderstorms. Warm moist air from the Gulf of Mexico and dry cool air from Canada. When these two air masses meet they create instability in the atmosphere. A change in wind direction and speed. Along with increasing height the air spins 2-6 miles wide and cause a tornado. A natural disaster if you will most of the moist will start things up, some of the key ingredients putting into an unstable atmosphere is warm and moist air at low

There are not big rain drops during the beginning of most tornados that occur on Earth. Sometimes there are not any large raindrops during a tornado but most of the time sometime during the time that a tornado is active people on the ground will start to notice rain drops. Most of the rain that is received by a tornado occurs after the tornado is over though. This is due to the

“A lot of the (lightning) hot spots are tied to features in the terrain — slopes of mountain ranges, curved coastlines, combinations of those,” Dr Daniel Cecil from the Global Hydrology and Climate Centre’s lightning team told the BBC.
