January and
February are
more cloudy,
with occasional
cold fronts
followed by dry
northerly winds.
It is not
uncommon for
temperatures
to drop below
10 °C (50 °F)
in urban areas.
5. We can deduce the values after dragging the
sun in accordance with the blue chart. We select the
chart of the correct Latitude. Select the date line.
Select the hour line and mark its intersection with
the date line.
We read off from the concentric circles the
altitude angle. Lay a straight edge from the center of
the chart through the marked time point to the
perimeter scale and read off the azimuth angle.
6. CLIMATE
March and April can be
pleasant although there
are occasional spells of
high humidity. Fog and
drizzle are common on
high ground which is
exposed to the
southeast.
May to August are hot
and humid with
occasional

8. The psychometric
chart shows graphically
the variables relating to
water moisture in air.
Following are the
properties of moist air:
Dry bulb temperature,
Wet bulb temperature
Dew point etc.
The yellow region
contains the ideal
comfort level. The curve
lines bending above are
higher percentages of
relative humidity. Fifty
to twenty percent being
highlighted by the
comfort zone.
9. The wind speed is
often highlighted in
knots, here we utilize
km/h.
The diagram shows
high pressures of air
towards respected
sides.
The color saturation
identifies the
accumulation of time.
10. Diof tempurnal
temperature data shows
daily cycles enrapture
and radiation on the
site. The data typically
includes dry bulb
temperature, wet bulb
temperature, direct
solar radiation.
The lower window
shows conditions in
accordance with a
specific date.
11. This is a weekly
summary chart that
operates through the
three axis, x y and z.
It can also
decipher direct
radiation, diffused
radiation, and average
cloud cover.
This can be done
hourly, with respect to
radiation.
