Lecture Notes on Climatology By Page 7 of 45 is the first day of the spring season and as such this date is called as the spring equinox. Equinoxes mark the seasons of autumn and spring and are. The term Climatology of the middle atmosphere over the tropical region of India book applies to numerous types of low pressure areas, one of which is the extratropical descriptor extratropical signifies that this type of cyclone generally occurs outside the tropics and in the middle latitudes of Earth between 30° and 60° latitude.

They are termed mid-latitude cyclones if they form within those latitudes, or post-tropical cyclones if a tropical. Feb 01,  · Abstract The Jordan mean tropical sounding has provided a benchmark reference for representing the climatology of the tropical North Atlantic and Caribbean Sea atmosphere for over 50 years.

However Cited by: Abstract Many studies have commented on the presence of midtroposphere dry air layers in normally moist areas of the warm-pool region in the tropical western Pacific Ocean. In this study, 5 yr of relative humidity (RH) observations from the Atmospheric Infrared Sounder (AIRS) instrument aboard the Aqua satellite are analyzed to identify areas of anomalously dry air between and hPa over Cited by: 8.

Climate is the long-term average of weather, typically averaged over a period of 30 years. Some of the meteorological variables that are commonly measured are temperature, humidity, atmospheric pressure, wind, and a broader sense, climate is the state of the components of the climate system, which includes the ocean and ice on Earth.

A study on the variability of temperature in the tropical middle atmosphere over Thumba (8 32' N, 76 52' E), located at the southern part of India, has been carried out based on rocket.

As pointed out in the climatology section, preexisting SSTs >26 °C are a necessary but insufficient condition for tropical cyclogenesis. Once the tropical cyclone develops and translates over the tropical oceans, statistical models suggest that warm SSTs describe a large fraction of the variance (40–70%) associated with the intensification.

2) In India a tropical wet and dry climate is more common. Noticeably drier than areas with a tropical monsoon climate, it prevails over most of inland peninsular India except for a semi arid rain shadow east of the Western Ghats.

Superimposed on the low-pressure area (AMT) at hPa, a well-defined divergence was noticed at hPa over the northern India in The mean temperatures at 25, 50 and 60 km (middle atmosphere) over Thumba were cooler in than in Author: B. Mukherjee, C.

Kulkarni, K. Indira, K. Dani. Tropical Easterly Jet Stream. It occurs near the tropopause over Southeast Asia, India, and Africa during summer. This jet implies a deep layer of warm air to the north of the jet and colder air to the south over the Indian Ocean.

Polar-Night Jet Stream. It meanders through the upper stratosphere over the poles. Climatologically, the area under study (Figure 1) is located in the tropical Indian monsoon region in eastern monsoon season rainfall initiates in early June and continues through September.

There is very little rainfall during the winter season (Lohar and Pal, ).Monsoon season rainfall is of great concern to scientists in India because of its impact on the agricultural by: KEY BENEFIT: Taking the study of atmospheric science beyond the daily weather map, Climatology explores the broader impacts of weather and climate.

The authors cover multiple facets of climate, many of which play a significant role in everyday life—and examine many topics, such as past climates, that are seldom adequately covered in other introductions to the subject.

Modern Climatology - Full Text. Shih-Yu (Simon) Wang and Robert R. Gillies. Climatology, the study of climate, is no longer regarded as a single discipline that treats climate as something that fluctuates only within the unchanging boundaries described by historical statistics.

Region 3: Towering cumulus clouds in the lowest km meet the capping inversion. Region 4: The air in this subcloud layer (~m) has relative humidities between 75 and 80%. The CISK-like driving mechanism is not responsible for the tropical atmosphere’s motions. The southerly flow over middle‐east Asia is also well simulated by the model.

These results show that the monsoon low‐level flow is well captured by the model although with slight underestimation of strength of winds over the west Arabian Sea and over central by: Climate isn't the same thing as birminghamasphaltcontractor.comr is the condition of the atmosphere over a short period of time; climate is the average course of weather conditions for a particular location over a.

temperature data sets which cover the middle atmosphere (over altitudes - km). A number of middle atmosphere climatologies have been developed in the research community based on a variety of meteorological analyses and satellite data sets. Here we present comparisons between these climatological data sets for a number of basic.

Summary. During the last phase of the Indian Middle Atmosphere Programme everyday launchings of high altitude balloons were carried out at three locations i.e. Trivandrum (°N, °E), Hyderabad (°N, °E) and Bhubaneshwar (°N, °E) for measuring winds and temperature between 1 and 30 km altitude in a campaign mode from 23 January to 31 March Cited by: 7.

Tropical cyclone climatology over NIO region. Since hundreds of years, the Indian Ocean is a breeding basin for disastrous TCs associated with heavy rainfall, torrential wind and storm surges.

Cold dry winds blow from this region to the low-pressure areas over the oceans to the south. In summer, a low-pressure area develops over interior Asia as well as over northwestern India.

This causes a complete. Dec 30,  · Warm rain processes over tropical oceans and climate implications. and plays an important role in regulating the moisture content of the tropical atmosphere.

The three major oscillations in existing in the middle atmosphere (~ km) are gravity waves, atmospheric tides and planetary waves, distinguished mainly by wave periodicity. Tropical moist climates extend northward and southward from the equator to about 15 to 25° of latitude.

In these climates all months have average temperatures greater than 18° Celsius. the first three factors are most important in influencing a region's climate. and total rainfall over millimeters or greater. S.G. Philander, in Encyclopedia of Ocean Sciences (Second Edition), The Atmosphere.

The atmospheric circulation in low latitudes corresponds mainly to direct thermal circulations driven by convection over the regions with the highest surface temperatures.

Moisture-bearing trade winds converge onto these regions where the air rises in cumulus towers that provide plentiful rainfall locally. References for “The Asian Monsoon” book – Chapter 2.
