India is home to an extraordinary variety of climatic regions, ranging from tropical in the south to temperate in the Himalayan north, where elevated regions receive sustained winter snowfall. The nation's climate is strongly influenced by the Himalayas and the Thar Desert.Though the Tropic of Cancer—the boundary between the tropics and subtropics—passes through the middle of India, the bulk of the country can be regarded as climatically tropical.

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.
2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

By understanding these aspects, students can gain a comprehensive view of synthetic fiber production, its impact on society and the environment, and the potential for future innovations. Synthetic fibers play a crucial role in modern society, impacting various aspects of daily life, industry, and the environment. ynthetic fibers are integral to modern life, offering a range of benefits from cost-effectiveness and versatility to innovative applications and performance characteristics. While they pose environmental challenges, ongoing research and development aim to create more sustainable and eco-friendly alternatives. Understanding the importance of synthetic fibers helps in appreciating their role in the economy, industry, and daily life, while also emphasizing the need for sustainable practices and innovation.
2. CLIMATE
India has varied climatic conditions.
Very hot and very cold regions as well as regions with
very heavy rainfall and very scanty rainfall. A large part of
south Asia has tropical monsoon climate.
The climate has been influenced by its position, size
and relief features as well as on air, pressure and wind
condition.

12. Upper air circulation
Upper air circulation or jet stream are fast flowing,
narrow air currents found in the atmosphere.
The main jet streams are located near the tropopause,
the transition between the troposphere (where
temperature decreases with altitude) and
the stratosphere (where temperature increases with
altitude).
13. Upper air circulation
JET STREAM IN SUMMER
•An easterly jet stream is
formed towards the end of June
over the Indian Peninsula in the
south-west monsoon season.
•It has been found that this jet
stream is strong when
the monsoon is very active.
• When this jet stream shifts
further , towards north latitude,
weak monsoon conditions
prevail.
14. TIBET
Upper air circulation
JET STREAM IN WINTER
•Another sub-tropical westerly
jet stream is formed along the
latitude of 27 degrees North
during winter at an average
height of 12 Km.
•The velocity of this jet stream
decreases as it migrates to
north.
•This sub-tropical jet adds to
the thunder activity in north
and north-west India.
17. Cyclones
• Cyclones are hurricanes that
happen in this area. They
can cause a great deal of
damage.

Seasons
The Climate of India may be
divided into four seasons-
1) Winter - From December to
February
2) Summer - From March to May
3) South-West monsoons or
rainy season - June to September
4) Retreating monsoons -

known as break in the
monsoon.

► Low pressure region
shift from northern parts
of India towards south.
► Owing to the conditions
of high temperature and
humidity, the weather
becomes rather
oppressive. This is
commonly known as the
‘October heat’
RETREATING MONSOON SEASON
LOW PRESSURE
35. Nawomica Sahay, Cambridge school Bangalore
• The summer monsoon brings in moisture from the Indian Ocean and produces a
tremendous amount of rain. The moisture from winter monsoons are largely blocked
by the Himalayas.
36. ► The variability of rainfall is
computed with the help of
the following formula:
C.V.= Standard Deviation/
Mean * 100
► Variability of less than 25%
exist in Western coasts,
Western Ghats,

TEST YOUR KNOWLEDGE
42. • Mango showers are the pre-monsoon showers in
the Indian states of Karnataka and Kerala that help in
the ripening of mangoes. Also known as April rains or
Summer showers, they are a result of
thunderstorms over the Bay of Bengal. These summer
rains normally come in the second half of the month of
April, though the arrival is difficult to predict. The
showers prevent the mangoes from dropping
prematurely from trees and are crucial for the mango
cultivators of South india.
