AS Level Physical Geography - Atmosphere and WeatherArm Punyathorn
Weather influences every part of our daily life. Climate shapes our culture, our history and our civilization. The changes in wind, temperature, humidity can not be underestimated.
Upon the completion of this chapter, you will be able to:
Distinguish between weather and climate,
Explain the place to place distribution of temperature and rainfall in Ethiopia,
explain the time to time patterns of temperature and rainfall in Ethiopia,
Analyze climate and its implications on biophysical and socioeconomic aspects,
identify the causes, consequences and response mechanisms of climate change.
5.1 The concept of weather and climate
Both weather and climate are concepts about atmospheric conditions. The basic difference on them is duration and areal coverage.
Weather is atmospheric condition observed in a very specific area with a short term fluctuation, while
Climate is a prolonged(30-35years) atmospheric condition observed in a relatively wider geographic area.
Weather condition likely changed hour to hour, in a daily base or weakly but climate is relatively permanent.
Elements of Weather and Climate
Elements(components) of weather and climate are the following variables
Atmospheric temperature (how cold or hot is the atmosphere)
Precipitation (any kind of moisture falling from the atmosphere to the ground, mostly rainfall)
Air pressure (the weight exerted by the air)
Humidity (the level or proportion of water vapor within the atmosphere)
Sunshine (the duration and intensity of solar heat as well as light)
Wind (horizontal motion of air)
This presentation explores a brief idea about the structural and functional attributes of nucleotides, the structure and function of genetic materials along with the impact of UV rays and pH upon them.

Cancer cell metabolism: special Reference to Lactate PathwayAADYARAJPANDEY1
Normal Cell Metabolism:
Cellular respiration describes the series of steps that cells use to break down sugar and other chemicals to get the energy we need to function.
Energy is stored in the bonds of glucose and when glucose is broken down, much of that energy is released.
Cell utilize energy in the form of ATP.
The first step of respiration is called glycolysis. In a series of steps, glycolysis breaks glucose into two smaller molecules - a chemical called pyruvate. A small amount of ATP is formed during this process.
Most healthy cells continue the breakdown in a second process, called the Kreb's cycle. The Kreb's cycle allows cells to “burn” the pyruvates made in glycolysis to get more ATP.
The last step in the breakdown of glucose is called oxidative phosphorylation (Ox-Phos).
It takes place in specialized cell structures called mitochondria. This process produces a large amount of ATP. Importantly, cells need oxygen to complete oxidative phosphorylation.
If a cell completes only glycolysis, only 2 molecules of ATP are made per glucose. However, if the cell completes the entire respiration process (glycolysis - Kreb's - oxidative phosphorylation), about 36 molecules of ATP are created, giving it much more energy to use.
IN CANCER CELL:
Unlike healthy cells that "burn" the entire molecule of sugar to capture a large amount of energy as ATP, cancer cells are wasteful.
Cancer cells only partially break down sugar molecules. They overuse the first step of respiration, glycolysis. They frequently do not complete the second step, oxidative phosphorylation.
This results in only 2 molecules of ATP per each glucose molecule instead of the 36 or so ATPs healthy cells gain. As a result, cancer cells need to use a lot more sugar molecules to get enough energy to survive.

introduction to WARBERG PHENOMENA:
WARBURG EFFECT Usually, cancer cells are highly glycolytic (glucose addiction) and take up more glucose than do normal cells from outside.
Otto Heinrich Warburg (; 8 October 1883 – 1 August 1970) In 1931 was awarded the Nobel Prize in Physiology for his "discovery of the nature and mode of action of the respiratory enzyme.
WARNBURG EFFECT : cancer cells under aerobic (well-oxygenated) conditions to metabolize glucose to lactate (aerobic glycolysis) is known as the Warburg effect. Warburg made the observation that tumor slices consume glucose and secrete lactate at a higher rate than normal tissues.
Earliest Galaxies in the JADES Origins Field: Luminosity Function and Cosmic ...Sérgio Sacani
We characterize the earliest galaxy population in the JADES Origins Field (JOF), the deepest
imaging field observed with JWST. We make use of the ancillary Hubble optical images (5 filters
spanning 0.4−0.9µm) and novel JWST images with 14 filters spanning 0.8−5µm, including 7 mediumband filters, and reaching total exposure times of up to 46 hours per filter. We combine all our data
at > 2.3µm to construct an ultradeep image, reaching as deep as ≈ 31.4 AB mag in the stack and
30.3-31.0 AB mag (5σ, r = 0.1” circular aperture) in individual filters. We measure photometric
redshifts and use robust selection criteria to identify a sample of eight galaxy candidates at redshifts
z = 11.5 − 15. These objects show compact half-light radii of R1/2 ∼ 50 − 200pc, stellar masses of
M⋆ ∼ 107−108M⊙, and star-formation rates of SFR ∼ 0.1−1 M⊙ yr−1
. Our search finds no candidates
at 15 < z < 20, placing upper limits at these redshifts. We develop a forward modeling approach to
infer the properties of the evolving luminosity function without binning in redshift or luminosity that
marginalizes over the photometric redshift uncertainty of our candidate galaxies and incorporates the
impact of non-detections. We find a z = 12 luminosity function in good agreement with prior results,
and that the luminosity function normalization and UV luminosity density decline by a factor of ∼ 2.5
from z = 12 to z = 14. We discuss the possible implications of our results in the context of theoretical
models for evolution of the dark matter halo mass function.
Deep Behavioral Phenotyping in Systems Neuroscience for Functional Atlasing a...Ana Luísa Pinho
Functional Magnetic Resonance Imaging (fMRI) provides means to characterize brain activations in response to behavior. However, cognitive neuroscience has been limited to group-level effects referring to the performance of specific tasks. To obtain the functional profile of elementary cognitive mechanisms, the combination of brain responses to many tasks is required. Yet, to date, both structural atlases and parcellation-based activations do not fully account for cognitive function and still present several limitations. Further, they do not adapt overall to individual characteristics. In this talk, I will give an account of deep-behavioral phenotyping strategies, namely data-driven methods in large task-fMRI datasets, to optimize functional brain-data collection and improve inference of effects-of-interest related to mental processes. Key to this approach is the employment of fast multi-functional paradigms rich on features that can be well parametrized and, consequently, facilitate the creation of psycho-physiological constructs to be modelled with imaging data. Particular emphasis will be given to music stimuli when studying high-order cognitive mechanisms, due to their ecological nature and quality to enable complex behavior compounded by discrete entities. I will also discuss how deep-behavioral phenotyping and individualized models applied to neuroimaging data can better account for the subject-specific organization of domain-general cognitive systems in the human brain. Finally, the accumulation of functional brain signatures brings the possibility to clarify relationships among tasks and create a univocal link between brain systems and mental functions through: (1) the development of ontologies proposing an organization of cognitive processes; and (2) brain-network taxonomies describing functional specialization. To this end, tools to improve commensurability in cognitive science are necessary, such as public repositories, ontology-based platforms and automated meta-analysis tools. I will thus discuss some brain-atlasing resources currently under development, and their applicability in cognitive as well as clinical neuroscience.
2. Weather and Climate
• The average weather
conditions over the
year in a particular
location determine its
climate.
• “Climate is what you
expect, but weather
is what you get.”
3. The modern atmosphere
• Two most abundant gases: 78% N2 and 21% O2
– Neither of these gases influence weather phenomena
• Argon (< 1%) inert gas
• Water vapor (varies from 1 to 4%)
– Source of all clouds and precipitation
– Absorbs and releases latent heat during phase change
– Greenhouse gas (traps atmospheric heat)
• CO2 (.039% or 39 ppm) – Greenhouse gas
• Non-gaseous components: water droplets, dust,
pollen, soot and other particulates
– Act as condensation surfaces for water in atmosphere
– Block sunlight and act as a cooling agent.
5. Solar radiation and the atmosphere
• Much of the highest
frequencies (x-rays,
gamma rays) are
absorbed by oxygen
atoms in the
thermosphere and O2 gas
in the mesosphere.
• Much ultraviolet (uv)
absorbed by the ozone in
the stratosphere.
• Visible light waves (still
considered shortwave)
pass through atmosphere
and are absorbed by
earth.
7. Depletion of the ozone layer
• Ozone – O3 forms in the stratosphere and
absorbs UV energy, which can be harmful
• Halons and Chlorofluorocarbons (CFCs), – are
organic compounds that destroy ozone in the
ozone layer
8. Depletion of the ozone layer
• Ozone hole – reported in
1985 and linked to CFCs
in Antarctic ice clouds
• Many nations of the world
agreed to reduce or stop
use of these CFCs and
halons
• Most industrial countries
no longer produce CFCs.
• Since banning CFCs, the
hole may be decreasing
9. Ozone high and low
• The ozone layer in
the stratosphere is a
good thing because it
protects life on Earth
from harmful UV rays
• The Ozone in the
troposphere is a bad
thing because it
damages hearts and
lungs.
10. Thermal Structure of Atmosphere: Troposphere
• Extends to about 12 km
(40,000 ft) elevation
• All clouds & water vapor
and most weather
• Temperature decreases as
elevation increases,
because chief source of
heat is radiated heat from
the earth’s surface
• Tropopause: boundary
between troposphere and
stratosphere.
11. Environmental Lapse Rate
• Lapse rate: the rate at which air
temperature decreases with
altitude.
•The environmental lapse rate is the
overall temperature decrease in the
troposphere with altitude
•The normal environmental lapse
rate is 6.5°C/1000m, however
various factors can change this.
•The illustration shows an
environmental lapse rate of
0.5°C/100m, which equates to
5°C/1000m.
•Question 7, in the homework, uses
this concept.
12. Example problem using normal lapse
rate
It is 25 C at the surface. Under normal̊
conditions, what is the air temperature at 4
kilometers (4000 meters) above the surface.
The normal lapse rate is 6.5 C/1000m̊
a.21 C̊
b.19.5 C̊
c.Still 25 C̊
d.-1 C̊
13. Example problem using normal lapse
rate
It is 25 C at the surface. Under normal̊
conditions, what is the air temperature at 4
kilometers (4000 meters) above the surface.
The normal lapse rate is 6.5 C/1000m̊
a.21 C̊
b.19.5 C̊
c.Still 25 C̊
d.-1 C̊ (this is about 30 degrees F)
14. Thermal Structure of Atmosphere: Upper Layers
• Stratosphere – heated
primarily by solar radiation
– Ozone (O3) layer
absorbs UV energy,
causing temperatures
to rise
– Above 55km
(stratopause) temps
fall again
• Mesosphere – thin air
(can’t absorb energy), very
cold up to 80km
• Thermosphere – above
80km, temps rise rapidly
(to just below freezing!)
15. Earth rotates around an axis from the
North to South Pole
• Lines of latitude:
imaginary horizontal
rings around the axis
– Equator is at 00
latitude
– Geographic poles at 900
latitude
– Arctic and Antarctic
circles at 66.50
latitude
– Tropic of Cancer (N),
Capricorn (S) at 23.50
latitude, define tropics
16. Earth rotates around an axis from the
North to South Pole
• Lines of longitude (meridians):
imaginary vertical lines that run
north to south.
• Line through Greenwich,
England (Prime Meridian) at 00
longitude.
• Longitude increases both east
and west of Prime Meridian and
meets at 1800
longitude, the
International Date Line.
17. The Earth’s axis is tilted 23.50
from the
perpendicular to the orbital plane.
AXIS
Perpendicular to
orbital plane
In this picture, the northern hemisphere is tilted away from the
Sun. In 6 months, when the earth has orbited to the other
side of the Sun, the northern hemisphere will be tilted towards
the Sun.
18. On Earth, heat energy comes from light energy
• One energy “unit” can be concentrated in a relatively
small surface, or spread out over a large surface,
depending on the angle of incidence.
• The more the energy is spread out, the less heat it
generates.
Warmest (Direct) Less Warm Least Warm
19. The Seasons (N. Hemisphere)
• Summer is warm
– Sun is higher in the sky
so solar energy is more
concentrated.
– North Pole receives sun
all day long.
– Days are longer than
nights.
• Winter is cold
– Sun is lower in the sky.
– North Pole receives no
sunlight.
– Nights are longer than
days.
20. The Seasons (N. Hemisphere)
• Fall and Spring –
Vernal and Autumnal
Equinox
– Poles not tilted away
or towards the Sun.
– Both hemispheres
receive equal amounts
of solar energy.
– Days and nights are
the same length (12
hours).
21. Heat, Temperature, and Thermal Energy
•Thermal energy is an energy of the system due to the
motion of its atoms and molecules. Any system has
thermal energy even if it is isolated and not interacting
with its environment.
•Heat is energy transferred between the system and the
environment as they interact due to a difference in
temperature.
• Temperature quantifies the “hotness” or “coldness” of a
system. Although proportional to the thermal energy of a
system, it is not the same thing! A temperature difference
is required in order for heat to be transferred between the
system and the environment.
22. Methods of Heat Transfer
• Radiation is the heat-
transfer mechanism by
which solar energy
reaches our planet.
• Energy transferred by
radiation is called
electromagnetic
radiation and can travel
through a vacuum. This
radiation is NOT
radioactive!
• All radiation travels at
the speed of light in a
vacuum.
24. Laws Governing Radiation
1. All objects emit radiant energy. This
includes the Earth, and its polar ice caps.
2. For a given size, hot object emit more
energy than cold objects
3. The hotter the radiating body, the shorter
the maximum wavelength. Solar
radiation is called short-wave radiation
and Earth’s radiation is called long-wave
radiation .
25. Laws Governing Radiation
4. Objects that are good absorbers of
radiation are good emitters as well. The
Earth and the Sun absorb and radiate
with nearly 100% efficiency for their
respective temperatures
5. The gases of the atmosphere are not so
good. They absorb some wavelengths
and then re-emit it. They let other
wavelengths pass through with no
absorption.
26. When radiation strikes an Object
• Transmission (no change in direction or temperature)
• Scattering and Reflection (transmission in another
direction)
• Absorption, which is accompanied by change of
temperature for object absorbing the radiation.
28. Reflection and Albedo
• Reflection–electromagnetic radiation bouncing of
from a surface without absorption or emission, no
change in material or energy wavelength
• Albedo – proportional reflectance of a surface
– a perfect mirror has an albedo of 100%
– Glaciers & snowfields approach 80-90%
– Clouds – 50-55%
– Pavement and some buildings – only 10-15%
– Ocean only 5%! Water absorbs energy.
30. Absorption and Emission
• Absorption of radiation – electrons of absorbing
material are “excited” by increase in energy
– Increase in temperature; physical/chemical change
– Examples: sunburn, cancer
• Emission of radiation – excited electrons return
to original state; radiation emitted as light or heat
– Example: earth absorbs short wave radiation from
sun (i.e. visible light) and emits longwave (infrared or
heat) into the atmosphere
32. the Radiation Balance
• Sun emits EM radiation of all wavelengths, but
primarily shortwave (i.e. light).
– Earth’s surface absorbs this energy
– Most is re-emitted upward, as heat (longwave)
• Greenhouse Effect
– “greenhouse gases” (water vapor, carbon dioxide,
methane, etc.) let shortwave energy pass, but absorb
and longwave energy radiated upward by the Earth.
– this longwave energy is re-radiated in all directions,
some of it returning to the Earth’s surface. This is
what keeps our atmosphere at a livable temperature
of about 15 degrees C (59 degrees F).
33.
34. Controlling Factors of Temperature
• Latitude: tropics are warmer and higher
latitudes are colder temperature due to
differences in the Sun’s angle and the
length of the day in these locations.
• Land and Water
• Altitude (troposphere temperature
decreases with altitude)
• Geographic position (windward coast vs.
leeward coast
• Cloud cover and albedo
37. Effect of westerlies carrying marine
air mass vs a continental air mass
Siberia (cold
arctic wind)
Pacific (moderate
ocean wind)
38. Effect of Clouds on Temperature;
cooling effect during the day,
warming effect at night
39. Global temperature distribution in January
• Red-warmer, blue-cooler
• Northern hemisphere colder than southern
• Coldest/warmest places are on continents
• Isotherms bend southward on land in northern
hemisphere – means inland is colder than ocean
40. Global temperature distribution in July
• red-warmer, blue-cooler
• Southern hemisphere colder than northern
• Coldest place Antarctic continent /warmest places are
continental deserts in the northern hemisphere
• Isotherms bend northward on land in northern
hemisphere, means inland is warmer than ocean
Editor's Notes
FIGURE 17.6 Composition of the modern atmosphere.
Figure 18.4 The albedos of common Earth surfaces vary greatly.
Figure 18.6 One half of the incoming solar radiation reaches the Earth’s surface. The atmosphere scatters, reflects, and absorbs the other half. All of the radiation absorbed by the Earth’s surface is re-radiated as long-wavelength heat radiation.
Figure 18.7 The greenhouse effect can be viewed as a three-step process. Step 1: Rocks, soil, and water absorb short-wavelength solar radiation, and become warmer(orange lines). Step 2: The Earth re-radiates the energy as long-wavelength infrared heat rays (red lines). Step 3:Molecules in the atmosphere absorb some of the heat, and the atmosphere becomes warmer.
