Air pressure. Relationships between pressure, density, and temperature (confined vs. unconfined gases). Measuring air pressure. Isobars. The pressure gradient force. Wind. Convection cell diagram. Out of the high, into the low. Local winds (sea/land breezes, mountain/valley breezes, Chinook/Santa Ana winds).
The atmosphere of Earth is composed of nitrogen (about 78%), oxygen (about 21%), argon (about 0.9%), carbon dioxide (0.04%) and other gases in trace amounts. Oxygen is used by most organisms for respiration; nitrogen is fixed by bacteria and lightning to produce ammonia used in the construction of nucleotides and amino acids; and carbon dioxide is used by plants, algae and cyanobacteria for photosynthesis. The atmosphere helps to protect living organisms from genetic damage by solar ultraviolet radiation, solar wind and cosmic rays. The current composition of the Earth's atmosphere is the product of billions of years of biochemical modification of the paleoatmosphere by living organisms.
Metfi 120 (introduction to Weather and Climato) Orline - Unit 2 Revie.pdfamericandigitalshop
Metfi 120 (introduction to Weather and Climato) Orline - Unit 2 Review Adiabatic processes in
the mountaln. The diagram below shows the lapse rates that air parcel will encounter while it is
forced to move over a mountain. If an alr parcel descends through the atmosphere the air will
heat at the dry adiabatic rate as it will necessarily be unsaturated. In summary, while rising air
cools at varying rates, descending air heats at a uniform rate. 16. Using the table below, fill in the
blanks for temperature and dew-point temperature at various helghts on the windward and
leeward sides of the mountain. Assume that the WALR is 0.5C/100m. (Note: temperature and
dew-paint drop together above LCL when a saturated air parcel rises and water vapor condonses.
In addition, start from the 500m at windward side 1000m1500m2000m Peak 2000m at leeward
side 1500m1000m500m Sea Level at leeward side.) 17. Compare to those of on the windward
side, how do air temperature and dew point on the leeward side? 18. From the previous question,
Why?
MEIR120 (introduction to Weather and CImate) Onine - Unit2 Review Here is a challenging
question. Assume that the wet adiabatic lapse rate (WALR) is 0.6C/100m. Fill the blanks in the
boxes in the figure. Here is how to get answers. 1. At the LCL, temperature (2C) and dew point
(2C) are the same. Until air parcel reaches LCL, temperature falls at the DALR (1.0C/100m). At
the LCL, temperature falls 25C from the surface (27C2C=25C). It means air parcel rises 2500m.
Thus LCL is 2500m. 2. Below the LCL, dew point changes at the Dew Point Lapse Rate (DPLR,
0.2C/100m ), it means that dew point has changed 5.0C(0.2C/100m2500m). Thus dew point at
the surface is 7C/100m 3. Above the LCL, both temperature and dew point fall at the WALR
(0.6C/100m). Atthe peak, dew point is 1C. It is 3C cooler than the LCL. It means air parcel rises
another 500m(0.6C/100m500m=3C). Thus, peak elevation is
3000m(LCL+500m=2500m+500m) 4. At the leeward side, temperature and dew point rise at the
DALR (1.0C/100m) and DPLR (0.2C/100m), respectively. Elevation has changed
2500m(3000m500m). Thus temperature and dew point rise 25C/100m and 5C. Thus, temperature
will be 24C(1C+25C) and dew point will be 4C(1C+5C).
Chapter 6: Precipitation and its formation Steps in the formation of precipitation according to the
Bergeron process. The Bergeron process relies on the fact that cloud droplets do not freeze until
they reach a temperature below the freezing point, and even then only in the presence of freezing
nuclei (solid particles that have a crystal form similar to that of ice). Because freezing nuclel are
much less abundant than condensation nuclei, many clouds exist in the liquid state while at
temperatures well below 0C. These are supercooled clouds. The freezing nuclei present promote
the formation of a few scattered ice crystals. Since lce crystals are more efficient absorbers of
water vapor, they consume the "excess" water vapor, which lowers the relative humid.

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.

Embracing GenAI - A Strategic ImperativePeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.
June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202

2. Essential Questions ? ? What is the atmosphere and what is its lowestlevel? How does atmospheric circulation work? What factors manipulate this circulation? What is the Coriolis Effect? What is atmospheric pressure? What factors effectit? What are standard atmosphere conditions? How does altitude relate to aircraft performance? The human body?
3. Important Terms Density – mass of something per volume Pressure – force of something per volume Coriolis Effect – the modification of air circulation patterns due to Earth’s rotation
4. Section I. Atmosphere Body of air that surrounds the Earth Always striving to achieve equilibrium – always in motion due to unequal heating of Earth’s surface High/low pressure Supports all forms of life on Earth
5. Composition of the Atmosphere 78% nitrogen, 21% oxygen, 1% other Water demo Troposphere Surface to 20,000 feet MSL Possesses most weather activity -2°C per 1,000 feet of altitude -1 inch of Hg per 1,000 feet of altitude Tropopause traps most weather inside troposphere
6. Atmospheric Circulation Warm air is thin (less dense) and has lower pressure, therefore it rises Cool air is thick (more dense) and has higher pressure, therefore it sinks Water/oil demo Unequal heating is due to Earth’s curved surface and that it rotates on a tilted axis Air is heated at equator, rises to pole, cools, and sinks back to equator – process repeats itself
7. Balloon Activity 1 Step 1. Put the balloon into the top of the bottle without dropping it. Seal the top of the bottle with the lip of the balloon. Step 2. Cover the hole and try to inflate the balloon. Step 3. Uncover the hole and try to inflate the balloon. What’s the difference? What happened during each trial?
8. Atmospheric Pressure The force exerted by the weight of air molecules Atmospheric circulation also affects atmospheric pressure A column of air would weigh more at sea level than at 18,000 feet Pressure can be affected by altitude, temperature, and density Pressure conditions affect aircraft performance, such as takeoffs, rates of climb, and landings Generally, most high pressure exists over polar regions and most low pressure exists over equatorial regions because of difference in temperature
9. Balloon Activity 2 Step 1. Blow up your balloon. Based on the previous slide, what can you conclude about the differences in air pressure?
10.
11. Section II. Coriolis Effect Pattern of air circulation is modified by rotation of Earth, called coriolis effect Northern Hemisphere: Air deflected to right Air rotates clockwise around high pressure areas Air rotates counterclockwise around low pressure areas Southern Hemisphere: Air deflected to left Air rotates counterclockwise around high pressure areas Air rotates clockwise around low pressure areas
12. Section II. Coriolis Effect Coriolis deflects more closer to the equator and less closer to the poles
13. Section III. Measurement of Atmosphere Pressure Measured in inches of mercury (Hg) by a barometer Atmospheric pressure also called barometric pressure Pressure of atmosphere pushes on a column of Hg that is advanced up a glass tube on a scale ISA – International Standard Atmosphere Standard pressure = 29.92’’ Hg (at sea level) Standard temperature = 15°C (59°F)
15. Section IV. Altitude and Atmospheric Pressure Atmospheric pressure decreases as altitude increases Pressure decreases by 1’’ Hg per every 1,000 feet Pressure decrease = density decrease Air density is changed by temperature which changes pressure
16. Section V. Altitude and Flight Takeoff/landing distances and climb rates increase at higher altitudes due to decreased atmospheric pressure More speed is required to takeoff if air is thinner (less of it exists in the same area) Propellers are also less efficient at higher altitudes – reduced rates of climb
17.
18. Section VI. Altitude and the Human Body Hypoxia Less oxygen exists at higher altitudes, even though concentration stays constant Hypoxia generally begins around 10,000 feet but can begin as low as 5,000 feet Cabin oxygen systems allow some planes to fly at very high altitudes
20. O 6 33% N 12 67% N 6 67% O 3 33% :Gas: :Quantity: :Concentration: N O N O Box A Box B Quantity vs. Concentration
21. Quiz Time!!! How does a barometer work? Atmospheric pressure exerts force on mercury which advances up a glass tube.
22. Quiz Time!!! Explain the difference between quantity and concentration. Quantity is the actual total amount of something within a given area, whereas concentration is the amount of that something in relation to the whole.
23. Quiz Time!!! How much does pressure decrease as altitude increases? 1’’ Hg per 1,000 feet of altitude
24. Quiz Time!!! What are standard atmosphere conditions? 29.92’’ Hg 15°C (59°F)
25. Quiz Time!!! Why is the atmosphere always in constant motion? It strives to achieve equilibrium by replacing low pressure with high pressure until the pressures are equal.
26. Quiz Time!!! What happens to warm air? What happens to cool air? Warm air: less dense/thinner, rises Cool air: more dense/thicker, sinks
27. Quiz Time!!! What is the composition of the atmosphere? 78% nitrogen 21% oxygen 1% other
28. Essential Questions ? ? What is the atmosphere and what is the bottom-most level? How does atmospheric circulation work? What factors manipulate this circulation? What is the Coriolis Effect? What is atmospheric pressure? What factors change it? What are standard atmosphere conditions? How does altitude relate to aircraft performance? The human body?
