5. What is it- magic Thermal?
Thermal is a collection of air rising through
the general air mass because it is lighter
than its surrounding
Air temperature
Pressure
Air vapor content
Water vapor weight 5/8
17. • Laps rate
• A) ELR
• B)DALR
• C)SALR
• Isobars lines
• Isotherms lines
• Dry adiabat lines
• Saturation
adiabat lines
• Saturation
mixing ratio lines
18. Understanding the sounding graph
Red- ELR
Green-Dew points
Yellow –isotherm
Purple – DALR
Blue- SALR
Braun –Saturation
mixing ratio lines
Black horizontal – isobar lines
Mixing ration- thermodynamic
function of state; the value of the
mixing ratio of saturated air at
the given temperature and
pressure.)

• ואלבידו השטח חימום
• חימום זווית
• יציאה זמן התרמיקות יציאת
• Triggers theory
• Lee side thermals
• קבועה תרמיקה
• הרוח השפעת

and rising cost of…..”
43. THERMALS IN MOUNAINS – BEST
SOURCE
אנבטי רוח
קטבטי רוח
Slope direction and time of the day
4 reasons of best source
44. Wind and thermals
Wind helps to thermal activity?
Wind strength/ thermal strength
“Strange” thermals
למדוד ?איך
Influence of thermals on the wind?
47. Triggers and Triggering
Triggers
a) hills or relief form
b) source with deferent temperature
c) wind
d)Shadow of clouds
e)Other thermal or sink of thermal
f)Any object
51. Factors influence on thermals
• Heating
• a) source of heating
• b) sun angle
• d) relief structure
• c) time of the day
• Triggers
• a) hills or relief form
• b) source with deferent temperature
• c) wind
• d) other
• Lapse rate
• Wind
64. Cloud streets/blue streets
Clouds street and dry thermals street
24 km/h at 2/3 of cloud heights
High pressure system with inversion
Passing the cold front
65. Flying over cloud street
1.Flying with wind direction
2. Just over one street
3. don’t hurry up
66. • Strong thermal
• Bid cloud
• Day without inversion
• Condensation before dew
point
• Sink before clouds
Sink under cloud
81. Kind Thermals and Dangerous
• Dust Devil (video2) (video)
• Sink air
• Turbulence
82. Cloud suck
• I'm sure most of us have been
there, pushing it just a little too
far under a cloud which was
looking so friendly ten minutes
ago. Next thing you know you're
accelerating towards it and
then... well... it all goes white!
• Cloud suck- video
83. Thermal flying principles
1. Look for the Patterns
2. Look for the weather/ terrain altering- change
the pattern
3. Compose formula of the particular flying day
same: triggers, sources
4. Each Found Thermal it is source and time to
understand where is next, possible the better
thermal
Main Motivation
is Exploring of
the Sky!!!
