The climate of a region is ultimately determined by the radiation energy of the sun, and its distribution and temporal fluctuations. The long-term state of the atmosphere is a function of a variety of interacting elements. They are: Solar radiation, Air masses, Pressure systems (and cyclone belts),Ocean Currents, and topography.
Weather & environmental changes affect RF signal severely. Ducting is one of the environmental phenomena that heavily deteriorate the radio performance. This document will give some ideas on root cause, impact & solutions of ducting on Radio Performance.
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)

Alt. GDG Cloud Southlake #33: Boule & Rebala: Effective AppSec in SDLC using ...James Anderson
Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).
Speakers:
Bob Boule
Robert Boule is a technology enthusiast with PASSION for technology and making things work along with a knack for helping others understand how things work. He comes with around 20 years of solution engineering experience in application security, software continuous delivery, and SaaS platforms.

2. Wind Rose Diagram
•The wind rose is the time honored method of
graphically presenting the wind conditions,
direction and speed, over a period of time at a
specific location.
•Accurate estimation of the dispersion of
pollutants in the atmosphere require a
knowledge of the frequency distribution of wind
directions as well as wind speed.
3. • To create a wind rose, average wind
direction and wind speed values are
collected at a site, at short intervals, over
a period of time, e.g. 1 week, 1 month, 1
year or longer.
• The collected wind data is then sorted by
wind direction so that the percentage of
time that the wind was blowing from each
direction can be determined.
4. • Presented in a circular format, the wind rose
shows the frequency of winds blowing from
particular directions over a particular
period.
• The length of each "spoke or segment" around
the circle is related to the frequency that the
wind blows from a particular direction per unit
time.
• Each concentric circle represents a different
frequency, starting from zero at the center to
increasing frequencies at the outer circles.
5. • A wind rose plot may contain additional
information, in that each spoke/segment is
broken down into color-coded bands that show
wind speed ranges.
• Wind roses typically use 16 cardinal
directions, such as north (N), NNE, NE, etc.,
although they may be subdivided into as many
as 32 directions.
• In terms of angle measurement in degrees,
North corresponds to 0°/360°, East to 90°,
South to 180° and West to 270°.

8. Uses of wind rose
1.Sailors use wind rose.
2.Architects do, or should, use wind rose information
for the siting of buildings and stadiums.
3. Wind-power "farms" (wind mills) do extensive
wind rose type studies prior to erecting their wind
turbines.
4. Also used for siting of industries in order to
minimize impact of air pollution on neighboring
cities
10. Plume Behaviour
1. Looping Plume
• High degree of convective
turbulence
• Super adiabatic lapse rate -strong instabilities
• Associated with clear daytime
conditions accompanied by
strong solar heating & light
winds
• High probability of high
concentrations at ground level
close to stack.
• Occurs in unstable
atmospheric conditions.
11.
12. 2. Coning Plume
• Stable with small-scale
turbulence
• Associated with
overcast moderate to
strong winds
• Roughly 10° cone
• Pollutants travel fairly
long distances before
reaching ground level
in significant amounts
• Occurs in neutral
atmospheric conditions
13.
14. 3. Fanning Plume
• Occurs under large negative
lapse rate
• Strong inversion at a
considerable distance above
the stack
• Extremely stable atmosphere
• Little turbulence
• If plume density is similar to
air, travels downwind at
approximately same elevation
15.
16. 4. Lofting Plume
• Favorable in the sense
that fewer impacts at
ground level.
• Pollutants go up into
environment.
• They are created when
atmospheric
conditions are
unstable above the
plume and stable
below.
17.
18. 5. Fumigation
• Most dangerous plume:
contaminants are all coming
down to ground level.
• They are created when
atmospheric conditions are
stable above the plume and
unstable below.
• This happens most often
after the daylight sun has
warmed the atmosphere,
which turns a night time
fanning plume into
fumigation for about a half
an hour.
19.
20. 6. Trapping plume
• When inversion exists both below and
above stack height, trapping results.
• The diffusion of pollutant is severely
restricted to the layer between the two
stable regions as shown in the figure.
21.
22. 7. Neutral Plume
• It tend to rise vertically until it reaches
air density similar to that of plume
itself. It is often converted to coning if
wind velocity is grater than 10 m/sec
and when cloud cover blocks solar
radiation.
26. Maximum Mixing Depth (MMD)
• The dispersion of pollutants in the lower
atmosphere is greatly aided by the convective and
turbulent mixing that takes place.
• The vertical extent to which this mixing takes
place depends on the environmental lapse rate
which varies diurnally, from season to season and
is also affected by topographical features.
• The depth of the convective mixing layer in which
vertical movement of pollutants is possible, is
called the maximum mixing depth (MMD).
27. • The maximum mixing depth (sometimes called the
mixing height) is obtained by projecting the dry
adiabatic lapse rate line to the point of intersection
with the atmospheric temperature profile
• These profiles are usually measured at night or early
in the morning.
• An air parcel at a temperature warmer than the
existing ground level temperature rises and cools
according to adiabatic lapse rate.
• The level where its temperature becomes equal to
the surrounding air gives the MMD value.
• Urban air pollution episodes are known to occur
when MMD is 1500 m or less.
30. Summary….of MMD
• Parcel heated by solar radiation at
earth’s surface
• Rises until temperature T’ = T
• T’ = particle’s temp
• T = atmospheric temp
• Achieves neutral equilibrium, no
tendency for further upward motion
31. DETERMINATION OF
MAXIMUM MIXING HEIGHT
• The following steps can be used to determine the
maximum mixing height for a day from a temperature
profile:
1. Plot the temperature profile (ELR), if needed.
2. Plot the maximum surface temperature for the day on
the graph for morning temperature profile.
3. Draw a dry adiabatic line (-1oC/100m) from the point of
maximum surface temperature to the point where it
interests the morning temperature profile.
4. Read the corresponding height above ground at the
point of intersection obtained in step 2. This is the
31
maximum mixing height for the day.
32. Practice problem (MMD)
Calculate the maximum mixing height from the
following early morning temperature data given
below:
The maximum surface temperature for the day was
15oC.
(Hint:- Follow steps given in previous slide. From
tabular values plot ELR and 150 C is air parcel temp in
contact with surface apply DALR to it)
Height (m)
Temperature (oC)
0 250 350 450 550 650
9.5 12.2 15.1 15.6 16.2 16.5

33. • A radiosonde (Sonde is French for probe) is a
unit for use in weather balloons that measures
various atmospheric parameters and
transmits them to a fixed receiver.
Radiosondes may operate at a radio frequency
of 403 MHz or 1680 MHz and both types
may be adjusted slightly higher or lower as
required.
• A rawinsonde is a radiosonde that is designed
to only measure wind speed and direction.
Rawinsondes are usually referred to as
Radiosondes.
